IE8 - Cookie Problem

IE8 - Cookie Problem

Hey all,

I'm setting up / testing a blog feed/roll on my site.  Basically, there is a form with a checkbox for each blog that can be viewed in the blog roll.  When the user clicks a checkbox, provided that it's not the very last checkbox (meaning that there would be no blogs selected), it sends a cookie with the updated information.

For example:
if blog 1 and 2 are checked, cookie contains:   "b1,b2"
and this cookie updates as soon as another box is checked.

Now, this works fine in firefox and chrome, the values persist when the page is reloaded.

However, when I check a box in IE and refresh the page, the cookie does not appear to have changed.

Next, I clicked a box, I closed IE completely and reopened it - the cookie had changed.  I think this means that IE is caching the cookie or something (until it's closed out), but I don't know how to stop it.

I'm using jQuery's cookie plugin to create the cookies in javascript and I'm reading them with php on page refresh.

Thanks in advance for your help!  Let me know if you need the code posted.

Edit:

Adding:
  1.     <META HTTP-EQUIV="Pragma" CONTENT="no-cache">
  2.     <META HTTP-EQUIV="Expires" CONTENT="-1">

Appears to have worked, however, I don't really want to use this because I'd like the majority of the content to cache.
