I wonder whether anyone has any clues to help.
I've got PHP Caching working find and the Cache Test comes back OK on the tests.
I was looking to get the faster speed from mod_rewrite.
I switched it on, updated the .htaccess file and the site 'appeared' to load reasonably fast (going by eye) however the Cahce Tests fail.
Any reason why PHP cahcing would be successful and mod_rewrite isn't?
