EZproxy Server Setup

NOTE: PDC secures its web site with SSL (Secure Sockets Layer). An SSL Certificate must be added to the EZproxy server to access secure online content without errors or browser warnings.

Please review the SSL Certificate options here. EZproxy can use a free, self-signed certificate, but if institutions choose this option, patrons will get browser warnings when they access the secure content. Institutions can inform their patrons to click through this warning to get to the content, but the recommended solution is a Certificate Authority Issued Certificate that prevents these browser warnings.

EZproxy logo

To set up remote access via EZproxy you must add the correct stanza to your EZproxy configuration. Configurations vary depending on which resources your institution has access to and how you want to connect. Sample configurations are provided below for these online resources.

EZproxy Configuration

Philosophy Documentation Center
Title Philosophy Documentation Center
Find var urlNeu=urlAlt.replace(/http:/, “https:”);
Replace var urlNeu=urlAlt.replace(/http:\/\/*?(\/.*)$/, “https://^^$1”);

EZproxy Starting Point URLs

Starting Point URL provides proxied access to an electronic resource that corresponds to a database stanza in the config.txt file. This URL consists of two parts, the proxy prefix and the target URL. The proxy prefix identifies your server and will always be the same. The target URL is the unique URL of the resource to which you are directing your users and providing proxied access. This URL must be configured correctly in your config.txt file for this starting point URL to work.


1. Connect to a list of Your Subscribed Titles on our site

Your Proxy Prefix + this Target URL:

2. Connect directly to a single title on our site

Your Proxy Prefix + this Target URL: of title

You can easily find the abbreviation of any publication on our site to set up the connection. For example, go to our alphabetical title list:

The part of the URL after the “=” sign is the abbreviation of the title. In this case it is “acorn”. The rest of the URL remains the same for each title.
