Debugging Mech,LWP...
Here is a good way to debug request->responses that are going between LWP and the web server.
use Aspect; my $pcut = call qr/LWP::UserAgent::send_request/; before { my $ctx = shift; print "req================\n"; print $ctx->params->[1]->as_string; } $pcut; after { my $ctx = shift; print "resp----------------\n"; print $ctx->return_value->headers->as_string; print "==================\n"; } $pcut; use WWW::Mechanize; my $m = WWW::Mechanize->new; $m->get("http://www.google.com");

req================ GET http://www.google.com Accept-Encoding: identity User-Agent: WWW-Mechanize/1.14 resp---------------- Cache-Control: private Date: Wed, 16 May 2007 17:08:09 GMT Server: GWS/2.1 Content-Length: 3971 Content-Type: text/html; charset=ISO-8859-1 Content-Type: text/html; charset=ISO-8859-1 Client-Date: Wed, 16 May 2007 17:10:46 GMT Client-Peer: x.x.x.x:80 Client-Response-Num: 1 Set-Cookie: PREF=ID=f76dcf3c38b51e16:TM=1179335289:LM=1179335289:S=WLL +o_3xLrawI8ife; expires=Sun, 17-Jan-2038 19:14:07 GMT; path=/; domain= +.google.com Title: Google ==================
You can use $c->return_value->as_string, if u want to get the content of the response too. And of course you need to install Aspect.pm module ;)
