Thread:Extension talk:MobileFrontend/File Cache

I'm a little confused regarding how MobileFrontend plays with the file cache. I've seen various reports suggesting that for the file cache to properly work when serving MobileFrontend and desktop versions of a page, you need to save the resulting files in separate directories to get the most out of it. [| Here] you can see an example of what people are talking about.

The reason I ask is that we recently upgraded from 1.17 to 1.24.1, and we found the file cache had become a major bottle neck all the sudden. And we realized the fact that deploying MobileFrontend (a major reason why we upgraded) could be leading to problems with the server figuring out what to serve out of cache given users looking at the same pages with different skins, especially (as in our case) we also have Varnish running.

Does that sound feasible?
