Since I want to trim down my htaccess I was wondering if its ok to remove the following parts in the htaccess which are mainly written by W3 Total Cache.
All the <IfModule > stuff. All the "RewriteEngine On" repetitions. All the file types listed in <FilesMatch > containers that are not used on my website (rtf, wav, mpg, divx, etc...).
I confirmed with my host provider that all the module directives are superfluous and I already tested that everything still works when they are erased. Same with the RewriteEngine On repetitions. However, in the wordpress W3 settings I get warning messags "Browser Cache is not properly configured" etc. I guess I can just ignore those? Thanks for any feedback.
