Credentials can be submitted to EZproxy as a query string as long as this is not specifically blocked in the user.txt file
http://ezproxy.abclib.org:2048/login?user=&pass=
The URL above will need to be updated to use the EZproxy name and specific login ports for the EZproxy server being accessed. The username and password from the uesr.txt file will need be populated as well after the equal symbols as well.
Note: This method will record the credentials in the EZproxy log files.
