I am currently switching between WPSC and W3TC in order to see who works best on husdal.com, but I have an odd problem. When using WPSC my source code says Super Cache, but my response header lists W3 Total Cache:
<!-- Dynamic page generated in xxx seconds. -->
<!-- Cached page generated by WP-Super-Cache on DATE TIME -->
<!-- Compression = gzip -->
X-Powered-By W3 Total Cache/0.9.2.2
I'm using mod rewrite with WPSC if that is any help in sorting this out. Interestingly, before switching to mod rewrite, the response header correctly said php caching, but switching back and forth between php caching and mod rewrite caching now doesn't change anything in the response header now.
Is this even a problem?
