When an alternate login page is configured through TRIRIGA, the default TRIRIGA login page still starts to load. You can almost miss it, but for about half a second before the alternate login page (as configured through the TRIRIGAWEB.properties file) loads, you can see the standard TRIRIGA login page with the username and password fields starting to appear but then it disappears, replaced by the alternate login page.
The index.html page would make a call to the server to see if it should display the alternate page. On slow connections, this would be seen as a ‘flash’. This change resolves an issue where the default TRIRIGA login page would briefly display before a custom login page was loaded.
