Is there a way to check is on cache (proxy_cache)

jose.montiel

Hi,

I'm trying to implement a location that can check if a resource is already on cache, and if so call proxy_pass, but if not return a message (something like "Not ready yet") and then call proxy_pass as background "detached" request.

This proxy_pass runs a long process, and I'd like not to make the user wait for it. Once the process is ready, it should be put on cache, so next time someone request this resource it is fetched from cache.

Is this possible?

Thanks in advance

why not use try_files and have the app write to htdocs?

These resources are mostly relevant a couple of days and take up too much space, so maintenance of these file are necessary. your solution or using proxy_store, will require to implement a maintenance process. This is why I want to use proxy_pass with proxy_cache, cache manager will take care of all of it, making the solution simpler.
