in reply to Help needed on HTTP redirects

Untested, but something like this should be well enough:
#!/usr/bin/perl use warnings; use strict; use CGI 'redirect'; use LWP::Simple 'head'; if(head('http://siteB.com')) { print redirect('http://siteB.com'); } else { print redirect('/404'); # already at siteA }
head should return true (and some info) only if the site asked is up and working. If it isn't enough, you might want to look at LWP head replacement, especially merlyn's answer.

You have moved into a dark place.
It is pitch black. You are likely to be eaten by a grue.

[1nickt]: The best way is to scope it tightly so it just goes away when you are finished with it.
[perldigious]: but... but... perldigious is the unvirtuous kind of lazy in this case. :-)
[perldigious]: Just kidding. Thanks 1nickt, I'll go ahead and do it the right way. An extra set of brackets and a little extra indentation isn't too much to ask.
[karlgoethebier]: perldigious: perhaps a block if you are paranoid ;-)
[choroba]: but undef %hash and %hash = () both work, too, but the first one keeps the memory allocated, while the latter makes it available for other parts of the program.
[choroba]: iirc
