Login forms are not displaying after changing http to https

Okay, so if you're seeing some content, there's a very good chance that you're experiencing what I call "the proxy effect". Basically, an HTTP request is generally a method (GET, POST), a URL path, and then a bunch of headers. An HTTP response is a status (200 OK), some headers, and then some payload. Inside that payload, and in some cases inside headers, URLs are either presented as relative (ex. /images/mycat.png) or absolute (ex. http://test.domain.com/images/mycat.png). Since you're virtualizing the application with a proxy server, and in this case actually changing the scheme, there's a very real possibility that the server isn't aware of this and is presenting absolute URLs to the client that reflect what it thinks is the correct address. In other words, if it worked with HTTP but now fails partially with HTTPS, there's a very good chance that the HTML content the client is receiving contains URL references to HTTP:// content, which are now not accessible. The VERY BEST way to troubleshoot this is to first understand what's breaking. And to do that you need a client side capture utility like Fiddler or HTTPWatch to observe the HTTP traffic from the client's perspective. If in the capture you see the browser try (and fail) to access an HTTP:// resource, it's a fair bet that some previous response contained that bad URL. If you know where it's coming from, you'll be able to effectively fix it with an iRule.
