What is Cookie Munging?

Cookie Munging is a concept of ASP.Net which lets users to manage session variables if their browsers do not support cookies. By default, ASP.Net uses cookies to store session ID’s. But, as we all know that some browsers do not support cookies. To overcome from this ASP.Net uses ‘Cookie Munging’ to manage session variables without cookies.

How it works?

When user requests page from server ASP.Net adds encoded session ID to every href in page. When user clicks a link ASP.Net decodes that encoded session ID and passes it back to the page the user is requesting. Now, the requesting page can use that ID to set or retrieve any session variables. This all happens automatically, if detects that the users browser do not support cookies.
