I have just installed WP Super Cache in the mu-plugin folder. Then I also activated it by turning on the WP Cache and Super Cache.
Nevertheless, I can neither find the file in wp-content/cache/.htaccess, nor find any .htaccess with the rewrite rules supposedly to be added after activation.
When I did a test with http://ismyblogworking.com/, the result of before and after turning on WP Super Cache:
Your blog seems slow. It took 1.73 seconds to generate the page.
1730 ms page generation time
2450 ms page fetch time
WP Super Cache is active.
249 ms page generation time
979 ms page fetch time
Which seems like some improvement in the speed. And I could also locate the cached files in /wp-content/cache/supercache folder.
So my question is,
1. is Super Cache properly installed on my server?
2. do I need to copy those rewrite rules into a particular .htaccess file?
3. do I need to create wp-content/cache/.htaccess?
Thanks in advance.
