We have a solution that contains 2 sitemap links that don't link to an entity in CRM but rather link to a web resource in CRM whose sole purpose is to redirect to an external ASPX page.
Sitemap link --> Please wait page --> Redirect to ASPX page --> Use ASPX page inside CRM
This loads our page nicely inside of CRM and works great for our needs.
However... We have 2 of these links. When you navigate to one of these links from anywhere in CRM they load just fine on their own. When you navigate to one of these pages from the other one, we get a blank white page where nothing loads. Nothing on any browser debugging tools, I haven't seen anything in Fiddler. As far as I can tell, nothing happens at all.
Click Sitemap link 1 --> Please wait page redirects to page 1 --> Page displays correctly --> click Sitemap link 2 --> stare at blank white page.
This works the other way around as well...
Click Sitemap link 2 --> Please wait page redirects to page 2 --> Page displays correctly --> click Sitemap link 1 --> stare at blank white page.
I'm not sure what other information I can give. The page is a set of Kendo grids that is reaching outside of CRM for its data and building some usage reports. I don't really think there's anything special going on that would cause an issue in the page itself. Especially since we never get to the aspx page. We never even see the Please Wait web resource displayed. It's just a blank page with seemingly nothing going on.
This specific instance I'm using is an Office 365 CRM 2013 trial so it's a completely vanilla CRM with no other customizations outside of my solution.
Has anyone ever seen any behavior like I've outlined or have any ideas on how I could troubleshoot this?
