An authenticating proxy is one that requires the user to supply a username and password to access the destination server where the application is running. Typically, authenticating proxies set a cookie to detect whether the user has logged on (or been authenticated). The cookie is sent in all subsequent network requests to avoid further logon prompts.

The codebase and server URL values that are set up by the Oracle WebLogic Server installation process include $FMW_HOME/forms/java and /forms/lservlet. As these are under the document base of the page ($FMW_HOME/forms), authenticating proxies will work.
