Fastcgi cache how-to cache for logged-in users and make it custom for each user

Server NGINX
1

Hello,

Currently I’m doing cache using fastcgi_cache for non-logged-in users,
and
using ( if + fastcgi_no_cache + fastcgi_cache_bypass ) to pass logged-in
users directly to backend which is PHP-FPM.

this work good enough, but when PHP-FPM start hitting 500+ req/s the
slow/load start.

So what i’m thinking about is to create a cache for logged-in users and
each
user has it’s own cached files, is that possible? if yes can you please
provide me some tips about that. I’ve goggled a lot but nothing help
with
that.

the site running custom php cms with mysql and memcached and apc

Thanks.

Use the session ID as part of the cache key. I have a drupal config
that uses that:

Woow, It’s very useful tip,

Could you illustrate this in details .? , Also Does it need to change
the
way php cms run his own cookies .?

No I don’t think so. What may have to change is the regex in the map
directive that captures the session ID. It depends on how is
generated.

You just use something like that and then set the cache key:

The cache key.

fastcgi_cache_key $cache_uid@$host$request_uri;
