Forum: NGINX try_files based on file mtime?

Hi all,

I found nginx a little while ago and I've been working on a fast 
wordpress setup with it. One thing I'm having a problem with is serving 
cached pages with an expiration.

So I have this (simplified a bit):

        location / {
                # If it's a real static file just serve it, otherwise 
check the cache
                try_files $uri $uri/ @checksupercache;
        }

        location @checksupercache {
                # First check if user is logged in, etc, but let's 
assume not, so we want to serve the static cache if it exists
                # This is the point where I would like to check the 
file's mtime. If it's too old, use @gotoblog even though the file 
exists.
                try_files 
/wp-content/cache/supercache/$http_host/$uri/index.html @gotoblog;
        }

How do I implement that last part? Say I want cached pages to last 2 
minutes. Something like this would be perfect:
try_files 2m blah/blah/$uri @otherwise;

What's the best way to do this?

If there's not a great way right now, would this be better/easier for me 
to implement as a patch to try_files or as a separate module with a 
separate command?

Thanks!

Why not use the proxy/fastcgi cache ?

I thought about doing that first, but it seems difficult to let php 
control the cache, like deleting specific files or clearing the entire 
cache when certain events happen.

What about proxy/fastcgi store, instead?

Stored response from backend are saved to well know files, so you have
full control over them.

It's not a cache, however.

Hello stdragon,

solution already?
