Answer 1

Though it is quite old thread, I thought I would share how I do it.

Let's say sending page is a.aspx and destination page is b.aspx.

1. Collect user inputs in a.aspx. User clicks submit button which causes postback.
2. inside Button_click event of a.aspx, process volume data (for example save uploaded binary files). Determine link of the volume data and append that to end of request.form name-value string.
3. Encrypt the final name-value string and set it to a cookie.
4. Redirect to b.aspx
5. in b.aspx, retrieve that cookie, decrypt and you get all name-value pair. Now process them as usual.

Advantages: (a) b.aspx is shown in browser address bar. It enters in browser's history. Server.transfer do these. (b) It gives effect of post. Users can not see the name-value pair in querystring.
