- EZproxy Proxy-By-Hostname
The answer has to do with how EZproxy handles https URLs.
The "dashes" are used when processing an https URL so the entire hostname (https://www.somedb.com/) will be translated to one host www-somedb-com. This allows the wildcard certificate on your server (*. ezproxy.institution.edu) to be used to maintain HTTPS connectivity without browser warnings.
Example URL: https://ezproxy.institution.edu/login?url=https://www.somedb.com EZproxy rewritten URL: https://www-somedb-com.ezproxy.institution.edu/
