Using AEM 6.3 JEE forms (Windows - JBOSS - TurnKey installation)
Intent to change the default login page for workspace users. When i created a new css page the Content-Type in IE11 is downloaded as text/html. (Windows 10 - IE 11)
I also tried using the ClientLib in the JSP pages link to the etc/design section, but the compile css is still text/html instead of text/css.
[not sure if this is the answer] Somewhere is read about a setting in the dispatcher "ModMimeUsePathInfo". Not sure where this is configured as we currently directly call the AEM forms server and not using a dispatcher.
I runt the same in Firefox & Chrome. Both no issues. Clear cash, run on different machine, all to no avail.
