By default, LWP::UserAgent automatically follows redirects for any request except a POST. The redirect_ok() method controls this behavior: 
       $ua->redirect_ok
           This method is called by request() before it tries to
           do any redirects.  It should return a true value if a
           redirect is allowed to be performed. Subclasses might
           want to override this.

           The default implementation will return FALSE for POST
           request and TRUE for all others.

Recently I had to write a script which posted a form on a remote site, and then checked the text of the resulting page to make sure the post succeeded. Unfortunately, there was a redirect to that page.

First I tried a making a subclass with a new redirect_ok() that always returned 1. Unfortunately, LWP::UserAgent used a POST request for the redirect; the remote server returned a 405 error. I ended up writing a redirect_ok() which replaced the POST request object in @_ with a new one that did a GET instead. Ugly, but it worked!
