I am Having Issue with No Caching Sitemap pages

Oyr Dynamic Caching caches URLs and not files. It is an NGINX reverse proxy that works based on headers. If an URL has to be cached, it must have the proper header. If it must be excluded or the cache busted – different headers. A single file does not posses those, it’s not being processed by the WordPress and the SG Optimizer plugin and is not cached by the Dynamic Caching.

This said, if you’re on Site Tools, you have the NGINX Direct Delivery optimization which handles static files including XML. By default, we cache XML files for 1 hour.

If you want to remove that cache, you need to disable the NGINX Direct Delivery and add a rule like that in your .htaccess file:

ExpiresByType text/xml “access plus 0 seconds”
ExpiresByType application/xml “access plus 0 seconds”

This said, I will discuss it with our DevOps team in order to change the defaults of that value and lower the 1 hour cache to something like 5 minutes because it shouldn’t be fully dynamic in case some plugin goes crazy.

If you’re on cPanel, just edit your .htaccess file chaning the default cachiing time for these.

Thanks for replying.

The problem is that that those expire rules you mentioned to add is already in the .htaccess.

Can’t you guys just add this ^/(.*)sitemap(.*).xml on the nginx ( this is what wp engine did for us for our other sites hosted there which resolved the issue)?

Also, i lowered the rss+xml and atom+xml to 600 seconds instead of 1 hour to see if that will help and that doesn’t work. Do you think lowering it to 0 will?
