[Cgi-session-user] problem with CGI::Session and mod_perl

[Senthil N. <rs...@gm...>]

Hi All,

I used CGI::Session in my application and stored data in the server and
retrieved it properly.

But later I moved to mod_perl for performance improvement and faced some
problems.

I see that the session is created and the session_id is sent as a cookie.
But when I store a value in the session with a key and try to load another
page and the same session is loaded but the data is lost. The same
application worked well on cgi/perl. But with mod_perl i see the session
data is lost.

Let me is there any problem is using CGI::Session with mod_perl.

Thanks
Senthil Nathan R

Thanks for the feedback. Please file a bug report for this in RT:

http://rt.cpan.org/NoAuth/Bugs.html?Dist=CGI-Session

Include as much detail as possible, including versions involved, and
steps to reproduce. ( It could be be pseudo-code if a working reduced case
isn't practical.)

It sounds like you are letting /us/ know. 

I'm using CGI::Session 3.95 with mod_perl, but I haven't tried yet with
the 4.x branch.

Has anyone else?

This usually means that your session object is not going out of scope.
 The session object doesn't write out it's changes to the data store
until the session object is destroyed.  In mod_perl, since the process
is persistent across multiple requests, it is possible to create a
global variable that never goes out of scope, and hence your session
data is never written out to the store.

You can either put an explicit $session->flush (or $session =3D undef;)
at the end of your code somewhere, or you can try to figure out why
your session object is not going out of scope.
