hey monks im having some trouble processing websites in parallel when the link redirects.. have a look at my code
#!/opt/csw/bin/perl -w print "Content-type: text/html\n\n"; require LWP::Parallel::UserAgent; use HTTP::Request; $timeout = 10; my @ns_headers = ( 'User-Agent' => 'Mozilla/4.76 [en] (Win98; U)', 'Accept' => 'text/html, text/plain,', 'Accept-Charset' => 'iso-8859-1,*,utf-8', 'Accept-Language' => 'en-US', ); my $reqs = [ HTTP::Request->new('GET', "http://www.google.ca", [@ns_headers]), HTTP::Request->new('GET', "http://advertising.microsoft.com/micros +oft-adcenter?s_int=US_20070401_livesearchResults_smh_001", [@ns_heade +rs]), ####UN-COMMENT THIS and it wont work ###### HTTP::Request->new('GET', +"http://advertising.microsoft.com/search/", [@ns_headers]), ]; my $pua = LWP::Parallel::UserAgent->new(); $pua->in_order (1); # handle requests in order of registration $pua->duplicates(0); # ignore duplicates $pua->timeout (2); # in seconds $pua->redirect (1); # follow redirects foreach my $req (@$reqs) { print "Registering '".$req->url."'<BR>\n"; if ( my $res = $pua->register ($req) ) { print STDERR $res->error_as_HTML; } } my $entries = $pua->wait(); foreach (keys %$entries) { my $res = $entries->{$_}->response; print "Answer for '",$res->request->url, "' was \t", $res->code,": + ", $res->message,"<BR>\n"; print "and the content is<BR>\n"; print "---------------------------<BR><TEXTAREA NAME='asdasd' ROWS +='5' COLS='80' WRAP='virtual'>\n"; print $res->content; print "</TEXTAREA>---------------------------<BR>\n"; }

by the way this code was taken from a website as an example here is where i found it http://search.cpan.org/~marclang/ParallelUserAgent-2.57/lib/LWP/Parallel.pm
update:
i'm new to perl, i have java knowledge and am applying it as best as i can to perl, i have no idea how to get any error messages. what's going wrong i think is the line: my $entries = $pua->wait(); i think that may be the problem, because nothing executes after that. if i input valid links in the requests the program runs fine and just prints out the content of the website. if i input a link that redirects to another link, then my program freezes up. thats about as best as i can describe my problem. like i said this code isn't fully mine, and im having trouble understanding it
