In this regard, a CGI is no different than any other Perl script. 
(The only *practical* difference is that CGI's need to respond fairly 
promptly or the Web server that invoked them will time out, so if the 
UPS site is slow you can get into trouble.  You can usually increase 
the timeout interval on your Web server to help alleviate this.)

When I have had to contact Web servers from Perl, I've used sockets, 
but that's because I am old fashioned and because it's been a while 
since I have done this in Perl.  It is my understanding that LWP is 
currently the "proper" way of doing this; you might start by looking 
at the docs for LWP::Simple.  If there's a better way, I'm sure folks 
on this list will let us know :-)
