Web Proxy - Web Proxies in Plain Speak

This article provides a brief explanation of web proxies.

The web proxy allows members of the University community to access restricted resources from off campus. This document is intended provide a brief, simple explanation of that process.


A web proxy works by proxying web requests (imagine that!). This that the proxy service, located somewhere else on the Internet, request a web page on behalf of a remote user, then forward the of the page (i.e., the web page) back to the user's browser. To the user the page appears as if it were requested directly.

To use the web proxy, users must (1) click on a link (or go to a website) which tells their browser to connect to a given site through web proxy, and (2) authenticate to the web proxy using their CNetID and CNet password so that it knows the request comes from an authorized member of the University community.[1]

Browser Configuration For Web Proxy

It is not necessary to configure your browser to use the University's proxy; however, people developing web pages which link to resources must format links to go through the web proxy (see Web Proxy - Registering Sites. You may also want to install a ! bookmarklet (see Web Proxy - Configuration for Off-Campus Access to University Resources) in case you encounter an old link.


[1] Note that the ability to log to the proxy does not imply automatic access to all proxied resources. Different resources can have different restrictions on who can access. As an example, many of the Library databases and journals are only licensed for use by current students, faculty, and University Hospitals staff; as a result, alumni are not allowed to access these through the proxy server, even though they can successfully authenticate.
