Change cache directory location?

Hi,

We run on Pantheon, where production sites run on a read-only file system except for the media sub-directory (to support uploads). This helps reduce the attack surface and is a really good idea.

Unfortunately, Autoptimize assumes all of wp-content is writeable, which isn’t true on Pantheon and other hosters who follow the same pattern. There seems to be no way to relocate the cache folder to a different location that is writeable.

Can you let me know if the cache folder can be moved? We’d love to pay for your product but this is a showstopper.
