I have a page that looks like this:

session_name("MyName");
session_start();

include("afile");

... more stuff here

include("adiffernetfile");

in the "afile" is the command ob_start("ob_gzhandler");
in the "adifferentfile" is the command  ob_end_flush();

when I open a browser and go to the page, the first time the page runs it gives an error: Warning: ob_gzhandler() [ref.outcontrol]: output handler 'ob_gzhandler' cannot be used twice in /blahblah/includes/adifferentfile.inc on line 23

on subsequent reloads this error does not come up.
If I comment out the session_name("MyName"); line, the error does not come up.
