Follow up: cookies and redirect

I can add some details more, after a bit of testing. A bit of history: I have a small switch-language-on-the-fly routine, which basically works like this: 1. Click on link 'language' in file_a.php 2. file_b.php gets called 2.a. it sets a language cookie (deletes previous in case) 2.b. redirects back to file_a.php using header("Location: " . $HTTP_SERVER_VARS["HTTP_REFERER"]); Obviously no output is produced by file_b.php, and this works like a charm if I use Communicator, but not with IE or Opera. I get no redirect. Now, it looks like the problem is directly related to HTTP_REFERER not being set (or received, better) by the browser. This surely happens with Opera on Linux (loading phpinfo() with Communicator clearly displays HTTP_REFERER (or HTTP_SERVER_VARS[HTTP_REFERER], as you prefer), while no sign of it comes up firing it up in Opera), but I suppose this applies to IE also (two problems in the same three-line routine looks like too much to me :) ). Now, I think I can try and solve this problem by passing along the calling filename (file_a.php, in the example) to file_b.php, and I'll make some more tests during the weekend, but I'd like to know if anyone can confirm such behaviour or had any problem like this.
