proxy\_cache workaround:

http{  
proxy\_cache\_path /cache keys\_zone=localcache:10m;  
limit\_zone perUri $uri 10m;  
}  
server {  
location /remote/ {  
try\_files $uri @fake @proxy-remote;  
}  
location @fake {  
root /notexists;  
}  
location @proxy-remote {  
limit\_conn perUri 1;  
proxy\_cache localcache;  
proxy\_cache\_valid any 999d;  
proxy\_cache\_key “remote$request\_uri”; # fix to suit your  
needs  
proxy\_set\_header Range “”; # don’t pass range requests  
to upstream in this section, otherwise response won’t be cached  
proxy\_pass upstream;  
error\_page 503 = @locked-remote;  
}  
location @locked-remote {  
# take your own. e.g.:  
proxy\_buffering off;  
proxy\_pass upstream;  
}  
# copy paste locations if you need (feel free to share common  
@fake)  
}

In case of proxy\_store just remove @fake and set right root in /remote/

This is just a PoC, so you have to change it up to your needs.  
It really works and nginx really rox =]  
Any questions? - Welcome

Sorry guys.  
There’s problem with workaround for proxy\_cache.  
So it works with proxy\_store only.
