Webpage errors after using offloading

From the limited information available here, it sounds like the page loaded from the HTTPS virtual server contained objects that tried to source from a site using hardcoded "http" scheme/protocol.

The best way to have this fixed is to get the application administrators/developers to change to use relative URLs to reference resources on the same site.

You can't do anything if the URLs are for a different host altogether.

Alternatively, you can create a stream profile to change every reference of http to https. See K8115: Overview of the Stream profile.
