Question

When I add a cookie through Response.cookies.add(cookie); My cookie will not be placed on the clients side until the client requests a page from my site. At the time of request .net will do some magic, place the cookie in the response and the client will store it. Is this true? If the above assumption is true I should be able to see unplaced cookies by cookie = response.cookies("foo"). Seems logical, but is it correct?

To sum it up.

I am placing a cookie, then later in the code before the request is served I am checking if the cookie is in the request.cookies("foo") if it is not I am checking the response.cookies("foo"). This method does not work. How would i go about reading a cookie before it is sent to the client side.

The actual question I need answered; Is there a way to view a cookies information before I send it to the browser? Something along the lines of check if cookie is on browser if not do some other check to see if it is waiting to be sent.If it is waiting to be sent read data on it

thank you very much.

If I understood the question correctly then you want to add a cookie to HttpResponse at some point after receiving a request from a client. Then at a later point of processing the request you want to access the same cookie again.

This quote might help you:

“After you add a cookie by using the HttpResponse.Cookies collection, the cookie is immediately available in the HttpRequest.Cookies collection, even if the response has not been sent to the client.”

(from http://msdn.microsoft.com/en-us/library/system.web.httpresponse.cookies.aspx)

I suggest you to process the cookie only at one point during the response. Thus you can check if it’s available in HttpRequest, and if not then add it to HttpResponse and invoke your additional logic.
