I am having problems getting the PERL LWP modules (Simple and UserAgent) working with Plesk 8.1 when the url I am trying to grab is on the Plesk server. Basically, I'm trying to grab the output from a PERL script on one name-based domain on the server, to use in a PERL script at a second name-based domain on the same server. This worked in previous versions of Plesk. The LWP modules work fine when the url I'm trying to grab is on a different server. The LWP modules also seem to work when I use IP-based hosting in Plesk, but this causes me some other problems, so I'd rather not do that. I'm not sure if this a firewall issue (and how/if it can be fixed) or if it is another configuration problem. Thanks for your help.
