IE 6.0SP1 with PHP Sessions in FRAMESETS - a bug?

[Guest]

Hello,

I'm developing CMS system in PHP4. CMS uses PHP sessions and consists of 3
frames loaded from main frameset file (index.php). In each of 4 files
(index.php + 3 frame files) I start PHP session on top of file - via
session_start() ) Recently I wanted to test part of the system on target
server and then I've noticed strange IE behaviour: when I try to open URL
with index.php sometimes all frames are loaded correctly but sometimes random
frames are not loaded - IE response is "Requested page cannot be displayed".
I've tested this on 4 client WinXP SP2 machines with IEs - same effect. (I'm
not using proxy, cookies have been deleted too). When I try to load index.php
and frames on FireFox 1.5 or Opera - it works - all frames ale ALWAYS loaded
correctly. After some investigation I dicovered that problem is connected
with execution session_start() in each of frames - when I remove this
function from PHP source of particular frame this frame is always loaded
correctly in IE. But this function is important for me - it gives me access
to PHP Session variables. What can be a reason of such beavaviour of IE?

Web Server: Linux 2.4.33 + Apache 2.2.3 + PHP 4.4.3 (module)

Problem solved

Problem was in ob_gzhandler option in PHP config file. It seems that IE 6.0
can't correctly support gzip output compression from Apache server on pages
with framesets. Disabling this function helped.
