Rewrite html files in root to directory - .htaccess

Question

Hi I'm in need of some assistance.
Problem:
I have now made my site multilingual using a CMS which processes everything at index.php
I am trying to redirect all .html pages being accessed from root,like
http://www.website.com/englishpage.html
I want to redirect it to
http://www.website.com/en/englishpage.html
and then a secondary redirect will dissect that information and send it to index.php which will then serve the correct page.
Right now, I'm getting too many redirect errors
# The Friendly URLs part
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*\.html)$ en/$1\.html [R=301,L]
RewriteRule ^(en|ru)?(\/)?(.*)$ index.php?c=$1&q=$3 [L,QSA]
what am i doing wrong here
thanks

Answer 1

(.*\.html) is not specific enough and therefore also matches /en/englishpage.html. It also keeps on adding .html to the end.
So /englishpage.html redirect to /en/englishpage.html.html, which redirect to /en/en/englishpage.html.html.html etc.
To fix both problems:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)\.html$ en/$1\.html [R=301,L]
RewriteRule ^((en|ru)/)?(.*)$ index.php?c=$1&q=$3 [L,QSA]
PS no need to escape a /
