mod rewrite: Remove www

[Fireball22]

Hello,

I've got the following mod_rewrite to redirect to different "virtual subfolders" depending on your language:

RewriteEngine on
RewriteRule ^(de¦en)$ http://www.%{HTTP_HOST}/$1/ [R=301,L]
RewriteRule ^(de¦en)/(index\.php)?$ index.php?language=$1 [QSA,L]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(de¦en)/(.*)$ $2?language=$1 [QSA,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(de¦en)/(.*)$ $2 [L]
RewriteCond %{HTTP_HOST} !^www\.[^.:]+\.(co\.[a-z]{2}¦[a-z]{2,6})\.?(:[0-9]+)?$
RewriteRule (.*) http://www.%{HTTP_HOST}/$1 [R=301,L]

Now I want to redirect directly to the Domain itself and not anymore to the www.DOMAIN.

So I tried to change the code as follows:

RewriteEngine on
#Remove the "www." in the first RewriteRule
#Externally redirect; Add "www"
RewriteRule ^(de¦en)$ http://%{HTTP_HOST}/$1/ [R=301,L]
RewriteRule ^(de¦en)/(index\.php)?$ index.php?language=$1 [QSA,L]
# Rewrite all URL-paths in en/ and de/ subdirectories
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(de¦en)/(.*)$ $2?language=$1 [QSA,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(de¦en)/(.*)$ $2 [L]
#What should I do here?
# Externally redirect to add "www" and remove trailing periods
# and/or port numbers on requested non-www hostnames 
RewriteCond %{HTTP_HOST} !^www\.[^.:]+\.(co\.[a-z]{2}¦[a-z]{2,6})\.?(:[0-9]+)?$
RewriteRule (.*) http://www.%{HTTP_HOST}/$1 [R=301,L]

I am looking forward to your ideas!

I got an e-mail notification because of a new post, but unfortunately I can't see anything?
Is this a bug?

Looks like a bug. Please see the "report a problem" link at the bottom of every WebmasterWorld page.

Your rule changes do not reflect your stated goal. Working from the code in your original post, you'd need:

RewriteEngine on
#
# Externally redirect requests for non-canonical "www" subdomain to non-www domain
RewriteCond %{HTTP_HOST} ^www\.([^.:]+\.(co\.[a-z]{2}¦[a-z]{2,6}))\.?(:[0-9]+)?$
RewriteRule (.*) http://%1/$1/ [R=301,L]
#
# Internally rewrite URL-path requests for /<language>/ or /<language>/index.php
# to script filepath /index.php?language=<language>
RewriteRule ^(de¦en)/(index\.php)?$ index.php?language=$1 [QSA,L]
#
# If requested URL-path /<language>/<anything> does NOT resolve to an existing directory,
# internally rewrite those requests to the filepath /<anything>?language=<language>
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(de¦en)/(.*)$ $2?language=$1 [QSA,L]
#
# If requested URL-path /<language>/<anything> does NOT resolve to an existing
# file, internally rewrite those requests to the filepath /<anything>
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(de¦en)/(.*)$ $2 [L]

I should note that the logic of your last two rules does not seem correct. The rules will work as I described in the comments, but it is unlikely that the last rule will ever execute. The last rule will only be invoked if the requested URL-path *exists* as a directory, but does NOT exist as a file, and if that requested URL-path does not match the conditions required to invoke the first of the three internal rewrite rules.

It wont work with the way it is written right now. Someone maybe will fix it?

@jdMorgan
Thank you very much for your professional help!
You are exactly right, I will try it as soon as possible!

@vetzkov
Did you replace the broken pipes?

I am sorry, but I wasn't able to test the new script!

I had uploaded the file via ftp an visited my homepage to check the script.
Unfortunately I wasn't able to visit more than one page of my website, because the Apache needed all the system memory at once for this request.
I removed the htaccess from my server, but I couldn't visit any site of my website.
The only resoluten was to restart Apache, and then it worked.

I don't know what is wrong, but I know, that this is a bug off course.
But I don't know if the script is wrong or my apache ;)
