Hi All,

I use Nginx on many sites and recently I thought to make use of  
fastcgi\_cache to capture response of PHP-FPM.

I want to put it in RAM (We have 32GB RAM. More than 50% of it is free)

I am confused as some article suggests - declaring “open\_file\_cache”  
before  
we can make use of fastcgi\_cache.

Can’t I directly use fastcgi\_cache on /run/cache ?

Please suggest.

No. “open\_file\_cache” is related to open file descriptors:

> **[Module ngx\_http\_core\_module](http://nginx.org/en/docs/http/ngx_http_core_module.html#open_file_cache)**

and “fastcgi\_cache”  
is only related to HTTP cache. They are two different things.

Yes, you can.

Thanks Joshua. 🙂

Got it working directly. It turned out to be easier than I thought.

Only thing complicated was no support for something like  
fastcgi\_cache\_purge  
in core

I need to remove official nginx & go through recompilation with

I hope someday, something like this will be part of Nginx core…
