Confusion about the HttpContext

[coollzh]

who can tell the detailed difference of:
HttpRuntime, Context, HttpContext.Current

sometimes, we can use Context Object instead of HttpContext.Current;
sometimes, we can user HttpRuntime Directly.....

 

[bruce barker]

HttpRuntime class has several static methods for accessing information about
the AppDomain asp.net loaded to run the pages.

because asp.net is thread agile (the thread may change during processing of
a request) thread local storage can not be used to keep info on the running
request. HttpContext is used for this.

HttpContext.Current is a static method that returns the HttpContext
associated with the calling thread (may return null)
Page.Context is a reference set to same object as HttpContext.Current, but
is a direct reference, no internal lookup required.

nice
i like that explanation. good job

 

[coollzh]

this is to say,the data from Context and the data from the
HttpContext.Current is the same one. in another words, the same value .
