Web server GET /names.nsf?Login requests prevented by default

For improved security, Domino 12 Web servers do not allow GET /names.nsf?Login requests by default.

If you used this type of request for a pre-12 server, when you upgrade to Domino 12, the following error is logged to the server console:
HTTP Web Server: You are forbidden to perform this operation [/names.nsf?login]

If you previously used /names.nsf?login to generate a login page, the best practice is to instead issue GET on a resource to force the server to generate the login page. For example, GET /names.nsf works in most cases.

While not recommended, the following notes.ini setting is available to revert to the pre-12 behavior and allow GET /names.nsf?Login requests:

DOMINO_REJECT_GET_LOGIN=0
