We have lots of occurrences of 'cache': 'false' in $.ajax invocations in our code, and only one occurrence of 'cache': true. Based on the documentation, it seems to me that 'cache' should pretty much never be set to false. But then again, we set it to the string 'false', not the boolean false.
This seems bad and in need of cleanup. Assigning to Timo.
