I could be completely wrong but ...

I can't see a problem here - although I would need to see the code.

There could be an issue with how IE and Netscape actually format the
header (i.e you may enter the above, but the header that gets sent may
be different) - but I could be completely wrong on this !

You may wish to look at http://sourceforge.net/projects/sessionmanager/

Which is URI transhandler / session manager that I wrote for a project
that never came about.  I may make another release that uses PerlSetVars
to configure the module if I get a chance to test it.

If this does not help, then post either the code, or a URL to the code
if its long, so that some of us can have a look.
