httpcontext and httpapplication

[phil2phil]

can someone tell me the difference between the httpcontext and
httpapplication object, they seems to have similar methods, such as
getting the Response, REquest, Server variables, are there times when
one should be used as opposed to the other?

Request/Server/Session are the same.

HttpApplication actually uses the context to return them...
Here's the code for the HttpApplication.Request

public HttpRequest Request
{
get
{
HttpRequest request1 = null;
if ((this._context != null) && !this._hideRequestResponse)
{
request1 = this._context.Request;
}
if (request1 == null)
{
throw new
HttpException(HttpRuntime.FormatResourceString("Request_not_available"));
}
return request1;
}
}


When you are in a page/usercontrol...just use Request and Response no need
to use Application.Request and HttpContext.Current.Request. They are
properties exposed by the Control class.

when you are in a non-control class, use
HttpContext.Current.Request/Response/....

Other than that, they do offer different functionality. They also offer
different storage capabilities, to learn more about it, check out:

storage differences)
