determine url redirectionby sylph001 (Sexton)

sylph001 has asked for the
wisdom of the Perl Monks concerning the following question:
I need your advices about detecting whether a link is redirected by a web site.
The web site requires my login account and password. I used lwp::useragent and did all the login interactions in my script and successfully got access to the main page as well as the resource link. I can send post request to the resource link directly and get the resource pictures as the response.
It worked for some time however recently I found the link is sometimes redirected to some account setting page. When this happened, the request to the resource link was redirected to a 'account confirm' page. If using web browser, I have to click the 'save' button on this page to be then redirected again to the resource.
Since the web site sometimes does the resource link redirection and sometimes doesn't, I'm considering to let the script deal with both cases. I used $response->is_success() to know if request works, but no idea as to the redirection things.
This is where I'm in huge need of your advices: is there any standard (or best way) to determine whether the resource link is redirected to the 'account' page instead of returning the real resource content? (Here I think we could regard the real resource content as zip files.)
