Post Method in Code-Behind C#

 Hi!
 
I have two different web applications.
I need to redirect from one to another, passing values in code-behind. But i don't know how to do this since I can't use querystring, neither javascript and the parameters that I need to pass can't be visible in the html part of the page. So how can I set parameters in the page code-behind and redirect it to another? And how would I get the values back on the second page?
 
Thanks!
