Where does a HttpContext value get stored

I would like to know, if I store a value using HttpContext.Current.Items.Add, where does it get stored? Is it on the Server, or client side like ViewState?

Will storing value开发者_开发技巧s in HttpContext.Current.Items.Add give problems in a Web farm situation?

Thanks in advance.

It is stored in the thread storage area.

I am not going into much detail for asynchronous processing when thread changes but in a context switch, context gets copied - I believe.

It is stored in the memory of the server and the value is available for the entire lifetime of the request.

I think the HTTPContext is stored on the server it comes from the HTTP request.

HttpContext.Current.Items is basically an IDictionary object (hashtable) whose scope is the life of the request.
