IE8 – JavaScript window.open invalidates session?

March 14, 2008

Anyone else having this problem?  On web sites (my own included) that open a new window with the JavaScript window.open method, that new window no longer has access to session variables from the parent.

In IE7 and FF2, if I have a page that:

Session[”MyVar”] = “Hello, world”;
     “<script language=’javascript’>window.open(‘RunReport.aspx’)</script>”);

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.

    @Eslam Kamal-

    Could you explain what you mean by “not permanent”?

    IE8 is still a beta, I havent bothered giving it a try as yet just bcz I’m already sort of sick with IE7. I really think MS should fix this issue coz its such a generic requirement. I suggest you should give them your feedback over this issue.

    This is still an issue with the release candidate (aka Beta 3). Other posts about it not being constant are correct. I have noticed that if I have no other browser windows open except my web app it seems to be ok. If other websites are open in other browser windows the sessions gets screwed. So far from a dev point of view I am hating IE 8 😦
