I am running mikrotik 3.22 with web proxy internal. I use secondary harddisk 150GB in size as cache drive. After running some couple days, the cache used is higher than max cache size which I set on web proxy settings. Please look at the images below:




So far the web proxy is so good, the traffic sent to clients almost 50% cache hits .

Is this a bug on 3.22 which cache used can exceed the max cache ?
I am considering to upgrade to 3.30.


Thank in advance.

I might be wrong but I think max cache size is the max size of an object that it will cache rather than the total overall size of the cache.

no, that's wrong. it's the max total cache size. not sure why it's not working in your version, will check in newer versions
