+Package pipeline implements an HTTP request/response middleware pipeline whose
+policy objects mutate an HTTP request's URL, query parameters, and/or headers before
+the request is sent over the wire.
+
+Not all policy objects mutate an HTTP request; some policy objects simply impact the
+flow of requests/responses by performing operations such as logging, retry policies,
+timeouts, failure injection, and deserialization of response payloads.
+
+Implementing the Policy Interface
+
+To implement a policy, define a struct that implements the pipeline.Policy interface's Do method. Your Do
+method is called when an HTTP request wants to be sent over the network. Your Do method can perform any
+operation(s) it desires. For example, it can log the outgoing request, mutate the URL, headers, and/or query
+parameters, inject a failure, etc. Your Do method must then forward the HTTP request to next Policy object
+in a linked-list ensuring that the remaining Policy objects perform their work. Ultimately, the last Policy
+object sends the HTTP request over the network (by calling the HTTPSender's Do method).
+
+When an HTTP response comes back, each Policy object in the linked-list gets a chance to process the response
+(in reverse order). The Policy object can log the response, retry the operation if due to a transient failure
+or timeout, deserialize the response body, etc. Ultimately, the last Policy object returns the HTTP response
+to the code that initiated the original HTTP request.
+
+Here is a template for how to define a pipeline.Policy object:
+
+   type myPolicy struct {
+      node   PolicyNode
+      // TODO: Add configuration/setting fields here (if desired)...
+   }
+
+   func (p *myPolicy) Do(ctx context.Context, request pipeline.Request) (pipeline.Response, error) {
+      // TODO: Mutate/process the HTTP request here...
+      response, err := p.node.Do(ctx, request)	// Forward HTTP request to next Policy & get HTTP response
+      // TODO: Mutate/process the HTTP response here...
+      return response, err	// Return response/error to previous Policy
+   }
+
+Implementing the Factory Interface
+
+Each Policy struct definition requires a factory struct definition that implements the pipeline.Factory interface's New
+method. The New method is called when application code wants to initiate a new HTTP request. Factory's New method is
+passed a pipeline.PolicyNode object which contains a reference to the owning pipeline.Pipeline object (discussed later) and
+a reference to the next Policy object in the linked list. The New method should create its corresponding Policy object
+passing it the PolicyNode and any other configuration/settings fields appropriate for the specific Policy object.
+
+Here is a template for how to define a pipeline.Policy object:
+
+   // NOTE: Once created & initialized, Factory objects should be goroutine-safe (ex: immutable);
+   // this allows reuse (efficient use of memory) and makes these objects usable by multiple goroutines concurrently.
+   type myPolicyFactory struct {
+      // TODO: Add any configuration/setting fields if desired...
+   }
+
+   func (f *myPolicyFactory) New(node pipeline.PolicyNode) Policy {
+      return &myPolicy{node: node} // TODO: Also initialize any configuration/setting fields here (if desired)...
+   }
+
+Using your Factory and Policy objects via a Pipeline
+
+To use the Factory and Policy objects, an application constructs a slice of Factory objects and passes
+this slice to the pipeline.NewPipeline function.
+
+   func NewPipeline(factories []pipeline.Factory, sender pipeline.HTTPSender) Pipeline
+
+This function also requires an object implementing the HTTPSender interface. For simple scenarios,
+passing nil for HTTPSender causes a standard Go http.Client object to be created and used to actually
+send the HTTP response over the network. For more advanced scenarios, you can pass your own HTTPSender
+object in. This allows sharing of http.Client objects or the use of custom-configured http.Client objects
+or other objects that can simulate the network requests for testing purposes.
+
+Now that you have a pipeline.Pipeline object, you can create a pipeline.Request object (which is a simple
+wrapper around Go's standard http.Request object) and pass it to Pipeline's Do method along with passing a
+context.Context for cancelling the HTTP request (if desired).
+
+   type Pipeline interface {
+      Do(ctx context.Context, methodFactory pipeline.Factory, request pipeline.Request) (pipeline.Response, error)
+   }
+
+Do iterates over the slice of Factory objects and tells each one to create its corresponding
+Policy object. After the linked-list of Policy objects have been created, Do calls the first
+Policy object passing it the Context & HTTP request parameters. These parameters now flow through
+all the Policy objects giving each object a chance to look at and/or mutate the HTTP request.
+The last Policy object sends the message over the network.
+
+When the network operation completes, the HTTP response and error return values pass
+back through the same Policy objects in reverse order. Most Policy objects ignore the
+response/error but some log the result, retry the operation (depending on the exact
+reason the operation failed), or deserialize the response's body. Your own Policy
+objects can do whatever they like when processing outgoing requests or incoming responses.
+
+Note that after an I/O request runs to completion, the Policy objects for that request
+are garbage collected. However, Pipeline object (like Factory objects) are goroutine-safe allowing
+them to be created once and reused over many I/O operations. This allows for efficient use of
+memory and also makes them safely usable by multiple goroutines concurrently.
+
+Inserting a Method-Specific Factory into the Linked-List of Policy Objects
+
+While Pipeline and Factory objects can be reused over many different operations, it is
+common to have special behavior for a specific operation/method. For example, a method
+may need to deserialize the response's body to an instance of a specific data type.
+To accommodate this, the Pipeline's Do method takes an additional method-specific
+Factory object. The Do method tells this Factory to create a Policy object and
+injects this method-specific Policy object into the linked-list of Policy objects.
+
+When creating a Pipeline object, the slice of Factory objects passed must have 1
+(and only 1) entry marking where the method-specific Factory should be injected.
+The Factory marker is obtained by calling the pipeline.MethodFactoryMarker() function:
+
+   func MethodFactoryMarker() pipeline.Factory
+
+Creating an HTTP Request Object
+
+The HTTP request object passed to Pipeline's Do method is not Go's http.Request struct.
+Instead, it is a pipeline.Request struct which is a simple wrapper around Go's standard
+http.Request. You create a pipeline.Request object by calling the pipeline.NewRequest function:
+
+   func NewRequest(method string, url url.URL, options pipeline.RequestOptions) (request pipeline.Request, err error)
+
+To this function, you must pass a pipeline.RequestOptions that looks like this:
+
+   type RequestOptions struct {
+      // The readable and seekable stream to be sent to the server as the request's body.
+      Body io.ReadSeeker
+
+      // The callback method (if not nil) to be invoked to report progress as the stream is uploaded in the HTTP request.
+      Progress ProgressReceiver
+   }
+
+The method and struct ensure that the request's body stream is a read/seekable stream.
+A seekable stream is required so that upon retry, the final Policy object can seek
+the stream back to the beginning before retrying the network request and re-uploading the
+body. In addition, you can associate a ProgressReceiver callback function which will be
+invoked periodically to report progress while bytes are being read from the body stream
+and sent over the network.
+
+Processing the HTTP Response
+
+When an HTTP response comes in from the network, a reference to Go's http.Response struct is
+embedded in a struct that implements the pipeline.Response interface:
+
+   type Response interface {
+      Response() *http.Response
+   }
+
+This interface is returned through all the Policy objects. Each Policy object can call the Response
+interface's Response method to examine (or mutate) the embedded http.Response object.
+
+A Policy object can internally define another struct (implementing the pipeline.Response interface)
+that embeds an http.Response and adds additional fields and return this structure to other Policy
+objects. This allows a Policy object to deserialize the body to some other struct and return the
+original http.Response and the additional struct back through the Policy chain. Other Policy objects
+can see the Response but cannot see the additional struct with the deserialized body. After all the
+Policy objects have returned, the pipeline.Response interface is returned by Pipeline's Do method.
+The caller of this method can perform a type assertion attempting to get back to the struct type
+really returned by the Policy object. If the type assertion is successful, the caller now has
+access to both the http.Response and the deserialized struct object.*/

+Package azblob allows you to manipulate Azure Storage containers and blobs objects.
+
+URL Types
+
+The most common types you'll work with are the XxxURL types. The methods of these types make requests
+against the Azure Storage Service.
+
+ - ServiceURL's          methods perform operations on a storage account.
+    - ContainerURL's     methods perform operations on an account's container.
+       - BlockBlobURL's  methods perform operations on a container's block blob.
+       - AppendBlobURL's methods perform operations on a container's append blob.
+       - PageBlobURL's   methods perform operations on a container's page blob.
+       - BlobURL's       methods perform operations on a container's blob regardless of the blob's type.
+
+Internally, each XxxURL object contains a URL and a request pipeline. The URL indicates the endpoint where each HTTP
+request is sent and the pipeline indicates how the outgoing HTTP request and incoming HTTP response is processed.
+The pipeline specifies things like retry policies, logging, deserialization of HTTP response payloads, and more.
+
+Pipelines are threadsafe and may be shared by multiple XxxURL objects. When you create a ServiceURL, you pass
+an initial pipeline. When you call ServiceURL's NewContainerURL method, the new ContainerURL object has its own
+URL but it shares the same pipeline as the parent ServiceURL object.
+
+To work with a blob, call one of ContainerURL's 4 NewXxxBlobURL methods depending on how you want to treat the blob.
+To treat the blob as a block blob, append blob, or page blob, call NewBlockBlobURL, NewAppendBlobURL, or NewPageBlobURL
+respectively. These three types are all identical except for the methods they expose; each type exposes the methods
+relevant to the type of blob represented. If you're not sure how you want to treat a blob, you can call NewBlobURL;
+this returns an object whose methods are relevant to any kind of blob. When you call ContainerURL's NewXxxBlobURL,
+the new XxxBlobURL object has its own URL but it shares the same pipeline as the parent ContainerURL object. You
+can easily switch between blob types (method sets) by calling a ToXxxBlobURL method.
+
+If you'd like to use a different pipeline with a ServiceURL, ContainerURL, or XxxBlobURL object, then call the XxxURL
+object's WithPipeline method passing in the desired pipeline. The WithPipeline methods create a new XxxURL object
+with the same URL as the original but with the specified pipeline.
+
+Note that XxxURL objects use little memory, are goroutine-safe, and many objects share the same pipeline. This means that
+XxxURL objects share a lot of system resources making them very efficient.
+
+All of XxxURL's methods that make HTTP requests return rich error handling information so you can discern network failures,
+transient failures, timeout failures, service failures, etc. See the StorageError interface for more information and an
+example of how to do deal with errors.
+
+URL and Shared Access Signature Manipulation
+
+The library includes a BlobURLParts type for deconstructing and reconstructing URLs. And you can use the following types
+for generating and parsing Shared Access Signature (SAS)
+ - Use the AccountSASSignatureValues type to create a SAS for a storage account.
+ - Use the BlobSASSignatureValues type to create a SAS for a container or blob.
+ - Use the SASQueryParameters type to turn signature values in to query parameres or to parse query parameters.
+
+To generate a SAS, you must use the SharedKeyCredential type.
+
+Credentials
+
+When creating a request pipeline, you must specify one of this package's credential types.
+ - Call the NewAnonymousCredential function for requests that contain a Shared Access Signature (SAS).
+ - Call the NewSharedKeyCredential function (with an account name & key) to access any account resources. You must also use this
+   to generate Shared Access Signatures.
+
+HTTP Request Policy Factories
+
+This package defines several request policy factories for use with the pipeline package.
+Most applications will not use these factories directly; instead, the NewPipeline
+function creates these factories, initializes them (via the PipelineOptions type)
+and returns a pipeline object for use by the XxxURL objects.
+
+However, for advanced scenarios, developers can access these policy factories directly
+and even create their own and then construct their own pipeline in order to affect HTTP
+requests and responses performed by the XxxURL objects. For example, developers can
+introduce their own logging, random failures, request recording & playback for fast
+testing, HTTP request pacing, alternate retry mechanisms, metering, metrics, etc. The
+possibilities are endless!
+
+Below are the request pipeline policy factory functions that are provided with this
+package:
+ - NewRetryPolicyFactory           Enables rich retry semantics for failed HTTP requests.
+ - NewRequestLogPolicyFactory      Enables rich logging support for HTTP requests/responses & failures.
+ - NewTelemetryPolicyFactory       Enables simple modification of the HTTP request's User-Agent header so each request reports the SDK version & language/runtime making the requests.
+ - NewUniqueRequestIDPolicyFactory Adds a x-ms-client-request-id header with a unique UUID value to an HTTP request to help with diagnosing failures.
+
+Also, note that all the NewXxxCredential functions return request policy factory objects which get injected into the pipeline.

-Package autorest implements an HTTP request pipeline suitable for use across multiple go-routines
-and provides the shared routines relied on by AutoRest (see https://github.com/Azure/autorest/)
-generated Go code.
-
-The package breaks sending and responding to HTTP requests into three phases: Preparing, Sending,
-and Responding. A typical pattern is:
-
-  req, err := Prepare(&http.Request{},
-    token.WithAuthorization())
-
-  resp, err := Send(req,
-    WithLogging(logger),
-    DoErrorIfStatusCode(http.StatusInternalServerError),
-    DoCloseIfError(),
-    DoRetryForAttempts(5, time.Second))
-
-  err = Respond(resp,
-    ByDiscardingBody(),
-    ByClosing())
-
-Each phase relies on decorators to modify and / or manage processing. Decorators may first modify
-and then pass the data along, pass the data first and then modify the result, or wrap themselves
-around passing the data (such as a logger might do). Decorators run in the order provided. For
-example, the following:
-
-  req, err := Prepare(&http.Request{},
-    WithBaseURL("https://microsoft.com/"),
-    WithPath("a"),
-    WithPath("b"),
-    WithPath("c"))
-
-will set the URL to:
-
-  https://microsoft.com/a/b/c
-
-Preparers and Responders may be shared and re-used (assuming the underlying decorators support
-sharing and re-use). Performant use is obtained by creating one or more Preparers and Responders
-shared among multiple go-routines, and a single Sender shared among multiple sending go-routines,
-all bound together by means of input / output channels.
-
-Decorators hold their passed state within a closure (such as the path components in the example
-above). Be careful to share Preparers and Responders only in a context where such held state
-applies. For example, it may not make sense to share a Preparer that applies a query string from a
-fixed set of values. Similarly, sharing a Responder that reads the response body into a passed
-struct (e.g., ByUnmarshallingJson) is likely incorrect.
-
-Lastly, the Swagger specification (https://swagger.io) that drives AutoRest
-(https://github.com/Azure/autorest/) precisely defines two date forms: date and date-time. The
-github.com/Azure/go-autorest/autorest/date package provides time.Time derivations to ensure
-correct parsing and formatting.
-
-Errors raised by autorest objects and methods will conform to the autorest.Error interface.
-
-See the included examples for more detail. For details on the suggested use of this package by
-generated clients, see the Client described below.
