WARNING: SSL not supported, entering non-anonymous area!

This proxy as installed does not support SSL, i.e. URLs that start with "https://". To support SSL, the proxy administrator needs to install the Net::SSLeay Perl module, and then this proxy will automatically support SSL (the CGIProxy site has more info). In the meantime, any browsing to an "https://" URL will be directly from your browser, and no longer anonymous.

Follow the link below to exit your anonymous browsing session, and continue to the URL non-anonymously.
