HttpContextBase Class

Definition

Serves as the base class for classes that contain HTTP-specific information about an individual HTTP request.

public ref class HttpContextBase abstract : IServiceProvider
public abstract class HttpContextBase : IServiceProvider
type HttpContextBase = class
    interface IServiceProvider
Public MustInherit Class HttpContextBase
Implements IServiceProvider

Remarks

The HttpContextBase class is an abstract class that contains the same members as the HttpContext class. The HttpContextBase class enables you to create derived classes that are like the HttpContext 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 with customized behavior that fulfills the scenario you are testing.

The HttpContextWrapper class derives from the HttpContextBase class. The HttpContextWrapper class serves as a wrapper for the HttpContext class. At run time, you typically use an instance of the HttpContextWrapper class to call members on the HttpContext object.

Constructors

HttpContextBase()

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

Properties

When overridden in a derived class, gets an array of errors (if any) that accumulated when an HTTP request was being processed.

AllowAsyncDuringSyncStages

When implemented in a derived class, gets or sets a value that indicates whether asynchronous operations are allowed during parts of ASP.NET request processing when they are not expected.

Application

When overridden in a derived class, gets the HttpApplicationState object for the current HTTP request.

ApplicationInstance

When overridden in a derived class, gets or sets the HttpApplication object for the current HTTP request.

AsyncPreloadMode

When implemented in a derived class, gets or sets an object that contains flags that pertain to asynchronous preload mode.

Cache

When overridden in a derived class, gets the Cache object for the current application domain.

When overridden in a derived class, gets the IHttpHandler object that represents the handler that is currently executing.

CurrentNotification

When overridden in a derived class, gets a RequestNotification value that indicates the HttpApplication event that is currently processing.

Error

When overridden in a derived class, gets the first error (if any) that accumulated when an HTTP request was being processed.

Handler

When overridden in a derived class, gets or sets the IHttpHandler object that is responsible for processing the HTTP request.

When overridden in a derived class, gets a value that indicates whether custom errors are enabled for the current HTTP request.

IsDebuggingEnabled

When overridden in a derived class, gets a value that indicates whether the current HTTP request is in debug mode.

IsPostNotification

When overridden in a derived class, gets a value that indicates whether an HttpApplication event has finished processing.

IsWebSocketRequest

When implemented in a derived class, gets a value that indicates whether the request is an AspNetWebSocket connection request.

IsWebSocketRequestUpgrading

When implemented in a derived class, gets a value that indicates whether the connection is upgrading from an HTTP connection to an AspNetWebSocket connection.

Items

When overridden in a derived class, gets a key/value collection that can be used to organize and share data between a module and a handler during an HTTP request.

PageInstrumentation

When implemented in a derived class, gets a reference to the page-instrumentation service instance for this request.

PreviousHandler

When overridden in a derived class, gets the IHttpHandler object for the parent handler.

Profile

When overridden in a derived class, gets the ProfileBase object for the current user profile.

Request

When overridden in a derived class, gets the HttpRequest object for the current HTTP request.

Response

When overridden in a derived class, gets the HttpResponse object for the current HTTP response.

Server

When overridden in a derived class, gets the HttpServerUtility object that provides methods that are used when Web requests are being processed.

Session

When overridden in a derived class, gets the HttpSessionState object for the current HTTP request.

SkipAuthorization

When overridden in a derived class, gets or sets a value that specifies whether the UrlAuthorizationModule object should skip the authorization check for the current request.

ThreadAbortOnTimeout

When implemented in a derived class, gets or sets a value that specifies whether the ASP.NET runtime should call Abort() on the thread that is servicing this request when the request times out.

Timestamp

When overridden in a derived class, gets the initial timestamp of the current HTTP request.

Trace

When overridden in a derived class, gets the TraceContext object for the current HTTP response.

User

When overridden in a derived class, gets or sets security information for the current HTTP request.

WebSocketNegotiatedProtocol

When implemented in a derived class, gets the negotiated protocol that was sent from the server to the client for an AspNetWebSocket connection.

WebSocketRequestedProtocols

When implemented in a derived class, gets the ordered list of protocols that were requested by the client.

Methods

RewritePath(String, String, String, Boolean)

When overridden in a derived class, rewrites the URL by using the specified path, path information, query string information, and a value that specifies whether the client file path is set to the rewrite path.
