title: PHP: session seems to be lost after header redirect only on IE
body: <p>I can't find a good answer for this anywhere.
  I have a login page, and after a good login it redirects to main page.
  In FF, and chrome - works perfect. On IE it doesn't work. I keep losing the session when I get to the main page.</p>
  
  <p>I have checked the following:
  - session_start at top
  - no blanks or anything befoer header redirect
  - one line before the redirect, IE knows the session user id, but after the redirect, just one line after the session start, it loses the session user id
  - I've checked it also on other computer - same results</p>
  
  <p>What is wrong with IE? or what could be wrong with my script ?
  Thanks </p>
