Hi Marko,
thanks for your reply. I tested with Yoast Sitemap and also with Google XMP Sitemaps Plugins both are not working. “Set Expires Header” is checked in HTML&XML Area.
Only pages in XML Format are not getting cached (but the cache files for sitemaps exist in the page_enhanced folder…) but for some reason nginx does not load them correctly?
Here is the part of page_enhanced in nginx.conf for me it looks good…
