Mechanize Redirect points to WWW::Mechanize::Plugin::FollowMetaRedirect.	[reply]

OK, here is what I did: First at the beginning of my program I have: `$agent->requests_redirectable( [] );` [download] Now here is where I click a continue button that loads the page that is supposed to redirect me to the final page (note that redirects are disabled and I am retrieving and then GETing the redirect URL manually): `$post_response = $agent->click('continue'); my $status = $agent->status(); if (($status >= 300) && ($status < 400)) { my $location = $agent->response()->header('Location'); if (defined $location) { print "Redirected to $location\n"; $post_response = $agent->get(URI->new_abs($location, $agent->b +ase())); printf("post_response is %s\n", $post_response->status_line); } }` [download] This seems to successfully capture the redirect URL and outputs the following (actual long hex strings and other info replaced with 'X'): `Redirected to /misc/XXXX/processocp.cgi?email=XXXX&back=httpXXXXX&spla +sh=X&vskey=XXXX post_response is 200 OK` [download] However I can tell from my program that is isn't successfully navigating to the final screen of the process, because when I run: `$post_response->decoded_content()` [download] I get (again, the info in the redirect URL has been replaced with 'X'): `<!DOCTYPE html> <html> <head> <meta content="text/html; charset=UTF-8" http-equiv="content-type"> <meta http-equiv="refresh" content="1;url=http://XXXX/processocp.cgi?e +mail=XXXXX&back=XXXXXX&vskey=XXXXX"> </head> <body> <div style="font-size: 1.5em; text-align: center; width: 300px; margin +: 0px auto; margin-top: 40px"> Processing...please wait<br/> </div> </body> </html>` [download] As you can see, it still seems to be stuck at the "processing.." screen, even though I told the program to "get" the redirect URL, i.e. the URL that would normally be automatically retrieved if redirects were enabled. What is going on here?	[reply] [d/l] [select]

OK, I solved it. The following does work: `$agent->follow_meta_redirect;` [download] but only if you do NOT also have this in your code: `$agent->requests_redirectable( [] );` [download] Alternately, you can also just parse the content returned by: `$post_response->decoded_content()` [download] when the page containing the redirect is first loaded, and get the redirect URL from that. Again, the key is that you must NOT have: `$agent->requests_redirectable( [] );` [download] in your code. I think it's strange that if you enable redirects you still must manually retrieve the redirect URL, and if you disable redirects then even manually retrieving the URL doesn't work.
