Well here is my .htaccess
file so far. I'll post it below:
AddType text/plain .phps
AddType application/x-tgz .tgz
AddType application/x-chrome-extension .crx
AddType application/x-web-app-manifest+json .webapp
<filesMatch "^(index|preactalpha)\.html$">
FileETag None
<ifModule mod_headers.c>
Header unset ETag
Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
Header set Pragma "no-cache"
Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT"
</ifModule>
</filesMatch>
<IfModule mod_rewrite.c>
RewriteEngine on
Error:

I put section 4. in the above section .3 "Add some code".
