I would like to work with Module Parameter DB_MODE in Permissions Module set to 1 so I can use cache to optimize the request to function allow_trusted in trusted table . But this table may change once in a while. Taking a look in the source, I didn't find how the cache is updated without my interaction. My doubt is if Cache is updated automatically or if I have to use MI_FIFO or change the source to do this. Thanks in advanced.
