At least with DBD::Informix, and probably with other drivers too, the normal
problem when something works from the command line but not via a web server
(browser) is the environment. When I say normal, I mean 99% of the time. In
general, web servers do not set the environment variables you need by default --
you have to configure them to do so. And, if you're running Perl scripts via
CGI, it is not very hard to validate the environment by creating a script that
prints the environment out. Apache even provides a test script in cgi-bin that
does precisely that.
