This is the configuration I use with Apache 2.2, some standard modules and a third party one, mod_proxy_html. Tor and polipo are installed on the server as well to make this work of course. I hope anyone finds this useful or has anything to add or share. Starting with a basic sample configuration from mod_proxy_html added to an SSL-enabled Apache vhost, I added:    SetOutputFilter INFLATE;DEFLATE    ProxyRemote * http://localhost:8118    ProxyRequests Off    <Location /sr/>        UseCanonicalName On        UseCanonicalPhysicalPort On        ProxyHTMLEnable On        ProxyPass http://ianxz6zefk72ulzz.onion/        ProxyPassReverse http://ianxz6zefk72ulzz.onion/        ProxyPassReverseCookieDomain ianxz6zefk72ulzz.onion myhostname.tld        ProxyPassReverseCookiePath / /sr/        ProxyHTMLURLMap http://www.dkn255hz262ypmii.onion https://myhostname.tld/sr_forums/        ProxyHTMLURLMap http://dkn255hz262ypmii.onion https://myhostname.tld/sr_forums/        ProxyHTMLURLMap http://www.ianxz6zefk72ulzz.onion https://myhostname.tld/sr/        ProxyHTMLURLMap http://ianxz6zefk72ulzz.onion https://myhostname.tld/sr/        ProxyHTMLURLMap / https://myhostname.tld/sr/ e,c    </Location>    <Location /sr_forums/>        UseCanonicalName On        UseCanonicalPhysicalPort On        ProxyHTMLEnable On        ProxyPass http://dkn255hz262ypmii.onion/        ProxyPassReverse http://dkn255hz262ypmii.onion/        ProxyPassReverseCookieDomain dkn255hz262ypmii.onion myhostname.tld        ProxyPassReverseCookiePath / /sr_forums/        ProxyHTMLExtended On        ProxyHTMLURLMap http://www.dkn255hz262ypmii.onion https://myhostname.tld/sr_forums/        ProxyHTMLURLMap http://dkn255hz262ypmii.onion https://myhostname.tld/sr_forums/        ProxyHTMLURLMap / https://myhostname.tld/sr_forums/ e,c    </Location>   <Proxy *>        AuthType basic        AuthName "Password Required"        AuthUserFile "/path/to/etc/apache22/sr.proxy.htpass"        Require valid-user    </Proxy>
