Forward/Reverse Proxying

This post is actually a brain dump of what i know so far from reading the numerous 'guides' out there..

Forward Proxy (e.g. Webmail)

The term Forward meant in the direction from "outside world" to "inside world".
Term to use in /usr/local/apache2/conf/httpd.conf : --> ProxyPass

Scenario

1) User --> webmail.com

2) therefore --> actually the framework is as follows

Webmail.com/

3) This is used to control incoming access (with respect to the web server)


Reverse Proxy (e.g. Internal programs accessing resources outside the network)

The term used is --> ProxyPassReverse

1) This is to control internal Application to access Internet / Extranet.

2) Can use this to control the type of access and the type of traffic allowed.
