Alright, I’m using form.target to open content in a new window. However, when I do this and then hit the back button on my browser, I find any entry resulting from a GET is doing another round trip to the server. This is a problem because session variables may have been changed in the interim, so the new GET no longer matches the old one.

I’m using C# and javascript for this web application, if it helps any.

This behavior occurs on IE8, but not on Firefox 10. Is there any way to prevent it in IE?

    I solved this problem by adding a semi-random ID as a querystring on the URL.

    I also added this to my OnInit event. For some reason explicitly setting the cache settings helps.

    Response.AppendHeader("Cache-Control", "private, max-age=600");

    Combined, this gave the page uniqueness and enforced the browser caching. This prevented the browser from always retrieving the most recent version of the page when encountering a GET operation in the browsing history.
