Question

How to make redirect from
site.com/ru/blablabla to
site.com/blablabla
??

And one more if on link site.com/en/blablabla server return 404,
then I need redirect to site.com/blablabla

my .htaccess:

    ########## Begin - Joomla! core SEF Section
#
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/index.php
RewriteCond %{REQUEST_URI} (/|\.php|\.html|\.htm|\.feed|\.pdf|\.raw|/[^.]*)$  [NC]
RewriteRule (.*) index.php
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
#
########## End - Joomla! core SEF Section

######### MY RULES #########
RewriteCond %{REQUEST_URI} \/ru\/(.*)
RewriteRule (.*)$ /%1

Answer 1

Can you remove all the lines under ######### MY RULES #########
line and put this line:

RewriteRule ^(en|ru)/(.*)$ /$2 [R,L]

This will take care of both /ru/foo and /en/foo URLs.
