ProxyHostnameEdit
ProxyHostnameEdit specifies a rule for renaming hostnames generated for proxy by hostname. If multiple ProxyHostnameEdit directives appear in config.txt, each is applied in the same order as they appear in config.txt.
This directive was originally created to allow the hostnames generated for proxy by hostname to be shortened to compensate for an early browser which could not handle hostnames that were longer than 63 characters in length. This restriction does not exist in any modern browsers.
The hostname presented to this directive for processing may include a letter and port number inserted at the beginning of the string, such as p8080-www.somedb.com for http://www.somedb.com:8080 or s8443-www.somedb.com for https://www.somedb.com:8443. The EZproxy server name is not presented as part of the string to edit.
ProxyHostnameEdit is a repeatable position-dependent config.txt directive.
