The W3 Total Cache Plugin Browser Cache .htaccess rules are easily moved from the .htaccess file to the main Apache httpd.conf, but first I had to generate them.
I installed and activated the W3 Total Cache plugin.
I setup the W3 Total Cache plugin Browser Cache options by turning the Browser Cache on via the General Settings page:
Go to “Performance” > “General Settings” : “Browser Cache” Enable Box Ticked.
That turns the Browser Cache on.
