Wrong page being displayed

[Graham Vickrage <gr...@gpmd.co.uk>]

I'm a newbie to Mod perl and have a odd problem.

I have installed apache2 2.0.53, perl 5.8.4 and MP2 2.0.0 and connect to
a postgresql database on a different machine (Apache:DBI & DBI &
DBD::Pg). All works well except that I seem to get old pages served on
new page requests. It would appear as if its some sort of caching issue
but I am not sure how to force a request. An example request would be

http://mysite.com/cgi-bin/displaypage.pl?page=2

And the next page would be 

http://mysite.com/cgi-bin/displaypage.pl?page=3

It shows previously viewed pages and with no particular pattern. Does
anyone know where I start looking to solve this one. The access logs are
displaying the correct request but the webserver is delivering previous
pages but not consistently????

Any help greatly appreciated.

I have figured out the problem. It was down to my globally scoped
variables in the pl scripts such as

my $q = new CGI; 

Once I specifically passed these into each procedure the problems
ceased.

Thanks for you help with this one.

The description of the problem really looks like that, so I could only
second Perrins suggestion to show us the code in question. I looks like
that you are hitting perl-processes which have a closure or something
else and in mod_perl the code is not recompiled everytime.

How about showing us some code?  Try to reduce it to a minimal piece
that demonstrates the problem.

Chances are good that you have a closure in your code that is making
your CGI object persist between requests.

Sometimes  something similar happens to me when I'm working on my dev 
machine and have automatic reloading turned on via Apache::Reload

Many times, Apache::Reload doesn't pick up the file change, or, for 
whatever reason, gets really screwed up and needs a reboot

doing a /usr/local/apache2/bin/apachectl stop / start solves that 
problem each time though -- sometimes a restart or graceful doesn't do 
it
