You said, "So, as I'm reading that, the explicit IP address or primary servername are OK, but you want to "return a pop-up" when the same URL comes in using an alternate servername." Maybe?
The explicit IP address and primary servernames are not displaying the pop-up (which is provided by going through the F5) but I need the pop-up to display.
So, the IP-address URL and the server-host URL both point to the actual server where the application resides. Hitting that IP doesn't present a pop-up.
The dns-alias URL points to the F5 (via DNS pointing to the F5 IP) where we get the 'nice' popup and then are brought to the application login.
Is there a way to force the IP-address URL and the server-host URL to redirect to the F5 URL? Ultimately, I need the pop up that is provided by hitting the F5 IP. So, I need all the various URLs to end up hitting the F5, or I need to lock down the URLs that don't provide the pop-up.
Not sure if I can accomplish this with Tomcat configuration, or if I need to look at something else. I don't think it can be configured via the F5 because the IP url and hostname URL don't go to the F5, they hit the application server directly.
I found a 'url rewrite filter' that looks promising, but it's a separate jar file to download and use which may not go over with security. But I can investigate that if it will work.
