Jump to navigation Jump to search used to be an HTTPS proxy, providing users a secure alternative to access the wiki projects of the Wikimedia Foundation.

After the main cluster was converted to support HTTPS for all traffic, was replaced with a simple redirect service for the old URL structure. For example, redirects to

Original service provided HTTPS/SSL secured access to the Wikimedia Foundation wikis, like Wikipedia, Wiktionary, etc.

The service ran on the singer host in the Pmtpa cluster, on Apache 2.2 with an SSL certificate and VirtualHost for Hits to this interface were then proxied to the internal load balancer and from there to regular Apaches via apache.pmtpa.wmnet, which serve the backend requests just like unencrypted hits.



Apache configuration is in /etc/apache2/ Running a custom-compiled Apache 2.2 in /usr/local/apache22

  • Wikis are proxied.
  • A special service IP is used.

Relevant config files...

  • /etc/apache2/sites-available/ on singer
  • wikimedia-ssl-backend.conf on all apaches

Modules proxy and proxy_http should be enabled with command a2enmod.

Proxy defs:

<Proxy *>
    Allow from all
ProxyRequests Off
ProxyPreserveHost On
ProxyPass /otrs !
ProxyPass /otrs-2.1.3 !
ProxyPass /otrs-web !
ProxyPass / http://apaches.pmtpa.wmnet/
ProxyVia On


For wikis, the frontend proxies to the general Apache servers in PMTPA. These hit a VHOST configured by wikimedia-ssl-backend.conf which does a rewrite match on the funny directories and sets an environment variable used by CommonSettings.php to decode the correct host.
