We have a ForeFront UAG server publishing two SP 2010 web apps externally. The first is the portal site, and the second is My Sites. UAG is terminating SSL and is also redirecting any port 80 requests, but ONLY for external connections (using split-DNS).
A problem we are having is that the Org Chart in My Sites appears to be using absolute URLs when it tries to load the thumbnail pictures for the org chart. When users come in through the UAG gateway, the thumbnail pictures load on MySites, but only when the browser is retrieving them with GET since UAG is doing the proxying for SSL to non-SSL. This causes the Org Chart to display the default thumbnail picture instead of the actual ones. We have confirmed that this only happens through UAG.
Is there a way to use relative URLs for the pictures, as this would satisfy the need for non-SSL inside, and SSL outside?
