Set proxy_cache_path on-demand

Set proxy_cache_path on-demand

l.m.cadastros

Hello everyone,

I have a scenario where the nginx serves multiple hosts and I load the configs per host on-demand.

One of the things that I have to load on-demand is caching. For the caching purpose, right now I'm writing an extra nginx config file specifying the proxy_cache_path like:

proxy_cache_path  /var/cache/nginx/example.org levels=1:2 keys_zone=example.org:5m

And after that I execute a nginx reload.

I was wondering if there is a way to specify proxy_cache_path on-demand without the nginx restart.

Thanks for the support.

Best,

Luis

No by default. You will need to specify the path per vhosts.

But I am thinking that, this could probably be made dynamic by using LUA code.. would be cool to hear if anyone have done this kind of scenario?

Regarding the reload, that should not be a problem as reload does not interrupt anything VS restart.

Hi Wasseem,

I hope you are doing well.

Thanks for you answer.

Wasseem, actually I'm doing it. I have s specific cache path per vhost. Like:

proxy_cache_path /var/cache/nginx/example1.org levels=1:2 keys_zone=example1.org:5m

proxy_cache_path /var/cache/nginx/example2.org levels=1:2 keys_zone=example2.org:5m

proxy_cache_path  /var/cache/nginx/example3.org levels=1:2 keys_zone=example3.org:5m
...

The problem is the number of vhosts that I have. It is getting bigger and it is taking too much time to reload and the reloads are getting more frequent (every time I add or remove a vhost I have to do a nginx reload). This is why I'm looking for an on-demand alternative to control the cache per vhost.

Best,

Luis
