When doing development in SP2010, I used to be able to edit files in _layouts/MySolution/... directly in 14 folder and see changes immediately (.js, .css files). That reduced time a lot while developing, and I could copy files back to solution after I am finished.
However, when I modify files in 15 folder in SP2013, SharePoint seems not to pick the changes immediately. It does so after recycling application pool, as well as after some period of time. So I suspect some sort of caching, that was not present in SP2010.
So the question - where is it and how do I turn it off for dev environment?
Note: it is not browser caching. I tried appending .css?QueryStringToForceCacheReload, as well as opening file in browser directly, Ctrl+F5 etc. Recycling app pool does help, but the whole point is not to wait for app pool recycling.
