NAME HTTP::CheckProxy - Perl module for testing for open proxies SYNOPSIS use HTTP::CheckProxy DESCRIPTION This module uses LWP to test the supplied IP address to see if it will promiscuosly proxy on port 80. Caution: this can have false alarms if you are on a network where you are supposed to go through a proxy, such as AOL -- but are you supposed to be running a webserver on such a network ? If you feed this an invalid ip address, LWP will complain. Note: while there is HTTP::ProxyCheck it is much slower, though it does a lot of input validation. HTTP::CheckProxy is intended to be useful in processing lots of candidate proxies and in recording useful information. To do this, make one object and repeatedly invoke the test() method with different IP addresses. USAGE my $open_proxy_test = HTTP::CheckProxy->new($ip); print "proxy test for $ip returns ".$open_proxy_test->code."\n"; print ($open_proxy_test->guilty? "guilty" : "innocent"); $open_proxy_test->test($ip2); print "proxy test for $ip2 returns ".$open_proxy_test->code."\n"; print ($open_proxy_test->guilty? "guilty" : "innocent"); BUGS SUPPORT Email bugs to the author. AUTHOR Dana Hudes CPAN ID: DHUDES dhudes@hudes.org http://www.hudes.org COPYRIGHT This program is free software licensed under the...

METHODS =cut ############################################# main pod documentation end ## new Usage : HTTP::CheckProxy->new($ip); Purpose : constructor Returns : object instance Argument : Mandatory first paramenter: name or ip address of candidate proxy. Do not include http:// . Optional second parameter: url (including the http://) to try to fetch. If this is invalid or unreachable the results of the test are meaningless, but this is NOT checked. Throws : We should probably throw an exception if the ip address under test is unreachable Comments : See Also : HTTPD::ADS::AbuseNotify for sending complaints about validated proxies and other abuse. guilty Usage : $open_proxy_test->guilty Purpose : Is in fact the tested host guilty of being an open proxy? Returns : true (its an open proxy) or false (it isn't) Argument : none Throws : nothing Comments : This method checks the return status code of the test. If an error code is returned, esp. code 500, the host is not guilty. If the status code is success, the host is guilty. See Also : HTTPD::ADS::AbuseNotify for sending complaints about validated proxies and other abuse. code Usage : $open_proxy_test->code Purpose : Return the status code of the proxy test Returns : HTTP status code Argument : none Throws : nothing Comments : See Also : HTTPD::ADS::AbuseNotify for sending complaints about validated proxies and other abuse. =cut sub code { my $self = shift; return ($self->get_response)->code(); } 1; #this line is important and will help the module return a true value __END__
