Yale's proxy server is called EZProxy and is hosted by OCLC.

• A YUL user is off-campus on their computer.
• The user goes to the library's proxied Databases A-Z List and discovers an e-resource they would like to access.
• They click on the e-resource link which has a special proxy prefix appended to the front of the URL.
• They will be asked to authenticate using their netID and password, via CAS and Shibboleth.
• They may be asked to sign in to Multifactor Authentication (DUO) if they haven't already.
• EZProxy passes along Yale’s registered IP address to the publisher and publisher checks against registered addresses.
• Publisher site confirms IP is Yale’s proxy server.
• The e-resource content is sent back to the user.
