Serves as the base class for classes that enable ASP.NET to read the HTTP values sent by a client during a Web request.

Derived: System.Web.HttpRequestWrapper

Remarks

The HttpRequestBase class is an abstract class that contains the same members as the HttpRequest class. The HttpRequestBase class enables you to create derived classes that are like the HttpRequest class, but that you can customize and that work outside the ASP.NET pipeline. When you perform unit testing, you typically use a derived class to implement members that have customized behavior that fulfills the scenario that you are testing.

The HttpRequestWrapper class derives from the HttpRequestBase class. The HttpRequestWrapper class serves as a wrapper for the HttpRequest class. At run time, you typically use an instance of the HttpRequestWrapper class to invoke members of the HttpRequest object.

Constructors

HttpRequestBase()

Initializes the class for use by an inherited class instance. This constructor can only be called by an inherited class.

Headers	When overridden in a derived class, gets the collection of HTTP headers that were sent by the client.
HttpChannelBinding	When overridden in a derived class, gets the ChannelBinding object of the current HttpWorkerRequest instance.
HttpMethod	When overridden in a derived class, gets the HTTP data-transfer method (such as `GET`, `POST`, or `HEAD`) that was used by the client.
InputStream	When overridden in a derived class, gets the contents of the incoming HTTP entity body.
IsAuthenticated	When overridden in a derived class, gets a value that indicates whether the request has been authenticated.

RawUrl	When overridden in a derived class, gets the complete URL of the current request.
ReadEntityBodyMode	When implemented in a derived class, gets a value that indicates whether the request entity body has been read, and if so, how it was read.
RequestContext	When overridden in a derived class, gets the RequestContext instance of the current request.
RequestType	When overridden in a derived class, gets or sets the HTTP data-transfer method (`GET` or `POST`) that was used by the client.
ServerVariables	When overridden in a derived class, gets a collection of Web server variables.
TimedOutToken	When implemented in a derived class, gets a CancellationToken object that is tripped when a request times out.
TlsTokenBindingInfo	Gets or sets the token binding information for this instance.
TotalBytes	When overridden in a derived class, gets the number of bytes in the current input stream.
Unvalidated	When implemented in a derived class, provides access to HTTP request values without triggering request validation.
Url	When overridden in a derived class, gets information about the URL of the current request.
UrlReferrer	When overridden in a derived class, gets information about the URL of the client request that linked to the current URL.
UserAgent	When overridden in a derived class, gets the complete user-agent string of the client.
UserHostAddress	When overridden in a derived class, gets the IP host address of the client.
UserHostName	When overridden in a derived class, gets the DNS name of the client.
UserLanguages	When overridden in a derived class, gets a sorted array of client language preferences.

Methods

Abort()	Forcibly terminates the underlying TCP connection, causing any outstanding I/O to fail.
BinaryRead(Int32)	When overridden in a derived class, performs a binary read of a specified number of bytes from the current input stream.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetBufferedInputStream()	When implemented in a derived class, gets a Stream object that can be used to read the incoming HTTP entity body.
GetBufferlessInputStream()	When implemented in a derived class, gets a Stream object that can be used to read the incoming HTTP entity body, optionally disabling the request length limit that is set in the MaxRequestLength property.
GetBufferlessInputStream(Boolean)	When implemented in a derived class, gets a Stream object that can be used to read the incoming HTTP entity body, optionally disabling the request length limit that is set in the MaxRequestLength property.
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
InsertEntityBody()	When implemented in a derived class, provides a copy of the HTTP request entity body to IIS.
InsertEntityBody(Byte[], Int32, Int32)	When implemented in a derived class, provides IIS with a copy of the HTTP request entity body and with information about the request entity object.
MapImageCoordinates(String)	When overridden in a derived class, maps an incoming image-field form parameter to appropriate x-coordinate and y-coordinate values.
MapPath(String)	When overridden in a derived class, maps the specified virtual path to a physical path on the server.
MapPath(String, String, Boolean)	When overridden in a derived class, maps the specified virtual path to a physical path on the server.
MapRawImageCoordinates(String)	Maps an incoming image field form parameter into appropriate x and y coordinate values.
