How is cache size to be understood ? #27

Closed lumpidu closed 1 year ago

In the example configuration cacheSize: 15 or cacheSize: 25 is stated, but I don't understand, what this number means:

Does it mean that geoblock caches only 15 or 25 IP addresses before updating the cache and reaching out to GeoJs.io ? This number would then be rather low and should be more like a few hundreds or thousands, right ?

Or does it mean, that it uses 15/25 x (some discrete size number) of memory for caching IP addresses ?

Hi @lumpidu

Yes you are right, the cache size means, that geoblock will remember the last x (e.g. 15) IP addresses. If a new x + 1 (e.g. 16th) address tries to connect, the oldest of the x (e.g. 15) addresses is ejected and GeoJs.io is contacted for the new IP.

Depending on the traffic your site will have, the number should be higher or lower. Since I host only some services at home for me and my family, my number is not very high.
