How many ports does EZproxy use with Proxy by hostname?

To avoid the arbitrary number of ports required for proxy by port, EZproxy can operate using the recommended proxy by hostname configuration. In proxy by hostname, EZproxy uses one to three pre-identified ports for all processing:

• one for http processing
• an optional one for https processing
• an optional one to allow old URLs to work if you move from using port 2048 to using port 80 for http

Using the example above, EZproxy will use rewritten URLs using the hostnames in config.txt and would represent the URLS above as follows:

• www.somedb.com as www.somedb.com.ezproxy.yourlib.org
• search.somedb.com as search.somedb.com.ezproxy.yourlib.org
• www.otherdb.com as www.otherdb.com.ezproxy.yourlib.org
• www.otherdb.com:180 as p180-www.otherdb.com.ezproxy.yourlib.org
