<p>Just published a guide on setting up Snac on an Ubuntu VM using NGINX Proxy Manager. Snac is an incredibly lightweight <a href="/tags/activitypub/" rel="tag">#ActivityPub</a> server.

Updated Version of the apache http caching setup for snac, including proxy media<br><br>I already wrote about caching <a href="https://snikket.de/social/menel/p/1738788742.236526" rel="nofollow">here</a>.<br>Now I extended what I cache a bit.<br>This was because after enabling the option to <a href="https://comam.es/snac-doc/snac.8.html#proxy_media" rel="nofollow">proxy media</a>, I&#x27;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/ ).<br>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&#x27;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)<br>This is the updated setup:<br>Enable the relevant modules:<br><br>a2enmod expires cache cache_disk<br><br>Be sure &quot;htcacheclean&quot; is running to clean up the old disk cache. (under debian see /etc/default/apache-htcacheclean or else the relevant systemd service or whatever)<br>Then add this to the httpd Virtualhost config:<br><br><p>&lt;LocationMatch &quot;^/social/[^/]+/[xys]/|^/social/nodeinfo_2_0&quot;&gt;<br>CacheEnable disk<br>Header set Cache-Control &quot;max-age=86400, public&quot; &quot;expr=%{REQUEST_STATUS} == 200&quot;<br>ExpiresActive On<br>ExpiresDefault &quot;access plus 86400 seconds&quot;<br>&lt;/LocationMatch&gt;<br></p>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.<br>Further reading and all options are explained under <a href="https://httpd.apache.org/docs/2.4/caching.html" rel="nofollow" class="ellipsis" title="httpd.apache.org/docs/2.4/caching.html"><span class="invisible">https://</span><span class="ellipsis">httpd.apache.org/docs/2.4/cach</span><span class="invisible">ing.html</span></a> (and ff)<br><br>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&#x27;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.
