Reverse proxying with Apache 2.2

Hi:

Sometimes you need to have Apache work as a reverse proxy, for example, to expose a web server behind a firewall to the public internet, or to add SSL. This is my short example on how to do it for the SSL case, but the other one should be similar.

<virtualhost 172.16.4.179:443>

        # Define location of SSl certificates and turn SSL On.

        SSLEngine on

        SSLOptions +StrictRequire

        SSLCertificateFile /etc/ssl/certs/server.crt

        SSLCertificateKeyFile /etc/ssl/private/server.key

        # Set up reverse proxy

        ProxyRequests Off

        

                Order deny,allow

                Allow from all

        

        # Expose /ESAL with contents of http://localhost:8080/ESAL

        ProxyPass /ESAL http://localhost:8080/ESAL

        ProxyPassReverse /ESAL http://localhost:8080/ESAL

        # Expose /limesurvey with contents of http://localhost/~eortega/limesurvey

        ProxyPass /limesurvey http://localhost/~eortega/limesurvey

        ProxyPassReverse /limesurvey http://localhost/~eortega/limesurvey

</virtualhost>

Here we are exposing through SSL sites that are published on non SSL locations (http://localhost:8080/ESAL/ and http://localhost/~eortega/limesurvey/).
