I don't think that replacing a traditional desktop app with a web app is an edge case. That's one of the main points of HTML5.

  I think what was meant by edge case is how you've architected this. Going by a statement in another comment of yours: > It is a pure SPA, you just have the option of opening multiple instances at the same time. Like I can open gmail in two tabs, but it's still an SPA. Gmail just runs the UI in the browser though, the actual work of processing, receiving and sending mail is not done in a tab. The tabs are just views into the system. It sounds like you are having one tab as both the client and the server, and separate tabs as clients to that other tab, which is pretty edge case. As someone else suggested, you could move the processing to the server, but I imagine that's not feasible because then you are centralizing the processing and you're paying for processing, not the people visiting. The more appropriate way to architect this (to my eyes, so take it for whatever you think it's worth) would be to use JS to manage tabs within the application (which you mentioned elsewhere already). The really simple way to implement this might be to have the JS tabs just contain an iframe to the prior implementation's real separate tab URL (since it already works that way, there's not likely to be any security issues you have to deal with).

  The way you architected it is uncommon, though. For example, with GMail, that you mentioned as achieving a similar effect, server communication is involved.
