Steps to reproduce the problem:
1. GPO Set disk cache directory to ${local_app_data}\Google\Chrome\User Data\Cache
2. GPO Set user data directory to ${profile}\AppData\Roaming\Google\Chrome\Profile. 

What is the expected behavior?
chrome://policy shows two different locations.  Would expect that a directory under appdata\local would have the cache directory.

What went wrong?
appdata\local is never touched.  Cache remains in AppData\Roaming

Did this work before? N/A

In order to have staff able to log in and use chrome on multiple computers at the same time, need to have chrome profile in roaming data, but disk IO is becoming a problem as the host server for profiles is constantly being hit for cache. I need local storage to handle the cache.  It would be great to have the option purge the cache after the session as well, as the user may never return to that computer.  Our roaming profiles are big only because google cache takes so much room up. Slows user logins down.  I've been trying to find a good solution for this for a long time.
