Peculiar performance linking images and inserting hyperlinks.  My dnn instance is under HostDomain/dnn.  If I navigate to hostdomain/dnn all is well.  I have an alias on portal0, call it MyDomain.  If I navigate to the alias, MyDomain, and log in everything appears normal until I try to edit an image in any module on any page.  If I right-click and select 'properties', what pops up is an image of the home page of the web-site.  If I go to Image Manager it does not recognize an image is already there and wants me to choose another...  Bizarre behavior.

If I attempt to add or modify a hyperlink, I also get a picture of the home page filling the box that looks like the hyperlink manager but has the web site title in the heading/banner...  More bizarre.

As disturbing as this behavior is, I can always navigate to HostDomain/dnn and everything is normal.

All my sites are at 5.6.2 and behaving the same.  It could have existed before at 5.5.1 and was not noticed as I only recently added portals and aliases to each impacted site.

The other peculiarity was that in order for the portal alias to fully work (access pages beyond the home page...) I had to set up a second portal alias; in addition to the expected MyDomain, I had to add an alias of Mydomain/dnn where dnn is the folder/directory under HostDomain where dnn was installed.  It seems to treat both MyDomain and MyDomain/dnn equivalently as HostDomain/dnn (?)  Is this behavior also new?  I might actually like doing that, and having it appear in the 'url' bar on the browser like it does, as long as it is 'expected' behavior.

Is it a secret how DNN processes these aliases or can I read about it more somewhere?

No urgency.  My curiosity is all that is currently at stake.

Thanks in advance.
