Hi,

Is it possible to pass data from a web form to mvc controller(except query string). My application has different IIS pools for web form project and mvc project. Asp.net session doesn't work in mvc.

Here's an example:
(In aspx)

string allowUpdate = "Yes";
Session["AllowUpdate"] = allowUpdate;

(In mvc controller, something like the following)

string allowUpdate = Session["AllowUpdate"];

Or

string allowUpdate = ViewData["AllowUpdate"];

Tried the above approaches but none of them worked. Could you please suggest some approach.
