EZproxy does not use the Apache web server. Some directives occasionally adopt an Apache-like syntax, but there is no direct use or integration of Apache into EZproxy.
EZproxy does use a few different libraries, such as OpenSSL and OpenLDAP. EZproxy servers support the endpoint /about that shows the various libraries and their versions. A user must be logged in as an administrator to see this page.
To see the About page, use a URL like this: https://EZproxyServer/about
Does the /about page report all dependent libraries?
EZproxy is built with static copies of all the libraries shown on the /about page, so none of these are external dependencies. The only non-static library dependencies are operating system libraries that can be seen using the ldd command.
So, if you want to see the operating system, non-static libraries associated with the EZproxy binary, use this command: ldd ezproxy. The command assumes you’ve renamed ezproxy-linux.bin to ezproxy.
