Hello @neovrnaz
Thank you for your inquiry and I am happy to assist you with this.
Indeed you can edit your .htaccess/nginx file but W3 Total Cache is offering much more features that cannot be done by simply editing the .htaccess/nginx file.
W3 Total Cache includes:
Page Cache
Browser Cache
Minify JS, CSS, HTML
Object Caching,
Database Cache,
CDN for various providers,
Cloudflare extension
Reverse Proxy,
Page Fragment Cache,
Support for Memcached, Redis, APC
Opcode cache support etc…
In one sentence, W3 Total Cache is the most complete caching solution.
I suggest you try it out!
Thank you!
