In IE7 and FF2, if I have a page that:
Session[”MyVar”] = “Hello, world”;
Then, RunReport.aspx could read Session[”MyVar”] and output ‘Hello, world’. That works fine.
Unfortunately, in IE8, the spawned window from window.open doesn’t have access to those session variables. I ran across this again reading through some Microsoft Training materials—the new window couldn’t tell I was logged in—and there was nothing (that I could figure out) to fix it.
Going into IE7 mode doesn’t appear to fix it either, which is a bummer.
