Updated Version of the apache http caching setup for snac, including proxy media

I already wrote about caching here.
Now I extended what I cache a bit.
This was because after enabling the option to proxy media, I've seen access to the file paths /x/ and /y/ in addition to the path were snac stores the media that I include in my own posts ( /s/ ).
There are two locations to proxy media, depending if you requests the media via the mastodon api or via the web. (/x/ and /y/), oh and I added the nodeinfo2.0 path too, because I've noticed it was queried all the time by a lot of instances and it gives me pleasure to see something cached handed out in the access logs. (I guess it is actually irrelevant for the system resources)
This is the updated setup:
Enable the relevant modules:

a2enmod expires cache cache_disk

Be sure "htcacheclean" is running to clean up the old disk cache. (under debian see /etc/default/apache-htcacheclean or else the relevant systemd service or whatever)
Then add this to the httpd Virtualhost config:

<LocationMatch "^/social/[^/]+/[xys]/|^/social/nodeinfo_2_0">
CacheEnable disk
Header set Cache-Control "max-age=86400, public" "expr=%{REQUEST_STATUS} == 200"
ExpiresActive On
ExpiresDefault "access plus 86400 seconds"
</LocationMatch>

This will use the disk cache to cache everything under the $username/s/, /x/ and /y/ paths, as well as for the /nodeinfo_2_0 path, utilizing mod_expires to generate the appropriate cache headers (for lazy ones like me). In this case caching it for 1 day.
Further reading and all options are explained under https://httpd.apache.org/docs/2.4/caching.html (and ff)

The Header that I set here, on the condition of Status code 200, is needed for the path /y/, because snac set no-cache on that location and mod_expires will honor that if we don't override it. I set it to the same Cache-Control value as mod_expires would. (I use mod_expires because it will additionally calculate the date and put that in the expires header. (hence the name I guess )
