Fetching objects from multiple upstreams with lua

fc23229

Hello,in my setting there is one major machine and a few storage machines. Static assets are spread through the storage machines. I would like the Nginx server on the major machine be able to

- get a specific asset by going through each storage machines until the asset is found

- save a copy of that asset in the major machine

Maybe I can use the try_files directive to go through the upstream machines, but I don't think I can save an additional copy in this way. Is it possible to do it with Lua?

I don't know what you mean by "save a copy". If you're using
ngx_proxy, then enabling its proxy_cache should already save a copy on
your file system out of the box.
