.htaccess rewrite without www AND redirect to subdirectory

Question

I'd like to redirect

• www.example.com/* to example.com/*

And at the same time redirect

• example.com/* to example.com/forum/*

But I also have /wiki/ and /blog/ and /style/, so I don't want to redirect

• example.com/style/* to example.com/forum/style/*

This is what I have at the moment, which is not working quite correctly:

Options +FollowSymLinks
RewriteEngine On

RewriteBase /

RewriteCond %{HTTP_HOST} !^example\.com$ [NC]
RewriteRule ^(.*)$ http://example.com/$1 [R=301,L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/forum/
RewriteRule ^(.*)$ forum/$1 [R=301,L]

Clarification: my question can be asked in a simpler way.

I'd like to redirect an empty REQUEST_URI or /, or a non-existent file only if it is in the root directory to /forum/.

Solution 1

Try this:

RewriteEngine On

RewriteCond %{HTTP_HOST} ^example\.com
RewriteRule ^(.*)$ http://example.com/$1 [R=301,QSA,L]

RewriteCond %{REQUEST_URI} !^/(wiki|blog|style|forum)
RewriteRule ^(.*)$ http://www.example.com/forum/$1 [R=301,QSA,L]

Solution 2

I would use these rules:

# redirect www.example.com to example.com
RewriteCond %{HTTP_HOST} ^www\.example\.com$
RewriteRule ^ http://example.com%{REQUEST_URI} [L,R=301]

# prefix everything but /forum/, /wiki/, /blog/, /style/ with /forum/ and rediret to it
RewriteRule !^(forum|wiki|blog|style)/ /forum%{REQUEST_URI} [L,R=301]

The second rule could additionally be replaced by this one to check the existence of the first path segment for every request.

# check if first segment of requested URI path is either missing
RewriteCond $0 ^$ [OR]
# or cannot be mapped to an existing directory
RewriteCond %{DOCUMENT_ROOT}$0/ !-d
RewriteRule ^[^/]* /forum%{REQUEST_URI} [L,R=301]

This was never answered. Did you ever find a way to redirect to forum without ending up at www.example.com instead of just example.com?

[Admin]

isn't there a way without specifying all the subdirectories? I currently have only 4, but there will probably be more later... Thanks for your answer!
