module to make SSL in POE easy and flexible
POE::Filter::SSL allows one to secure connections of POE::Wheel::ReadWrite with OpenSSL by a POE::Filter object, and behaves (beside of SSLing) as POE::Filter::Stream. . POE::Filter::SSL can be added, switched and removed during runtime, for example if you want to initiate SSL (see the SSL on an established connection example in SYNOPSIS) on an already established connection. You are able to combine POE::Filter::SSL with other filters, for example have a HTTPS server together with POE::Filter::HTTPD. . POE::Filter::SSL is based on Net::SSLeay, but got two XS functions which Net::SSLeay is missing.
