Right now I have the following code to redirect all non-www URLs to www URLs:

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

Besides that redirection, I also want to redirect all calls to /dev/ to dev.example.com. I've tried a bunch of different approaches but nothing has worked (the few that get close like ReplaceMatch will only redirect to the dev.example.com bit and will leave the rest as a query string).

Any ideas?

EDIT: Here's the full .htaccess for the root folder (a few rewritten for privacy reasons):

ErrorDocument 404 /404.html
AddType application/x-httpd-php .json
AddType application/x-httpd-php .xml

Options +FollowSymlinks
RewriteEngine On
RewriteBase /

# disables image hotlinking

RewriteCond %{HTTP_REFERER} !search\?q=cache [NC]
RewriteRule .*\.(jpe?g|gif|bmp|png)$ - [F]

# Stop htaccess rules from accessing these areas of the website.
RewriteRule ^(banner|boxart|cgi-bin|content|forums|includes|newsimages|newsimg|sidebar|union-files|google5e645385256c3a63.html) - [L]

RewriteRule (.*) /$1/ [R=301,L]

# Redirect old URLs to their new URLs

# Redirect non-WWW to WWW

RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]
RedirectMatch 301 ^/dev/(.*)$ http://dev.example.com/$1

# URL Directory Redirects
RewriteRule ^([^/]*)/$ /index.php?p=$1&urltype=slash [L,QSA]
RewriteRule ^([^/]*)/$ /index.php?p=$1&urltype=slash [L,QSA]
RewriteRule ^([^/]*)/([^/]*)/$ /index.php?p=$1&lv1d=$2 [L,QSA]
RewriteRule ^([^/]*)/([^/]*)/([^/]*)/$ /index.php?p=$1&lv1d=$2&lv2d=$3 [L,QSA]
RewriteRule ^([^/]*)/([^/]*)/([^/]*)/([^/]*)/$ /index.php?p=$1&lv1d=$2&lv2d=$3&lv3d=$4 [L,QSA]

# URL File Redirects
RewriteRule ^([^/]*)\.html$ /index.php?p=$1&urltype=dot [L,QSA]
RewriteRule ^([^/]*)/([^/]*)\.html$ /index.php?p=$1&lv1p=$2 [L,QSA]
RewriteRule ^([^/]*)/([^/]*)/([^/]*)\.html$ /index.php?p=$1&lv1d=$2&lv2p=$3 [L,QSA]
RewriteRule ^([^/]*)/([^/]*)/([^/]*)/([^/]*)\.html$ /index.php?p=$1&lv1d=$2&lv2d=$3&lv3p=$4 [L,QSA]

# For servers that support output compression, you should pick up a bit of speed but un-commenting the following lines.
php_flag zlib.output_compression On
php_value zlib.output_compression_level 5

The one in /dev/ is basically the same as this one, except that it has a password protection bit at the top and has a few redirects for some image folders that only reside on the root of the server.

So .. you have more than 1 .htaccess file: one in the root folder and one in /dev folder.

Where did you put rules from @Alex -- root or /dev .htaccess? Most likely in root. That is the reason why it did not worked.

Thing is -- if Apache sees rewrite rules in lower level folder, it will NOT execute them from parent folder UNLESS your lower level .htaccess has RewriteOptions inherit line: http://httpd.apache.org/docs/current/mod/mod_rewrite.html#rewriteoptions

Now, you have added the below code into the .htaccess:

RedirectMatch 301 ^/dev/(.*)$ http://dev.example.com/$1

This directive belongs to another module and gets executed anyway .. and it executes after mod_rewrite have already rewritten the URL. That's why you see real URLs after redirect.

The rule below should work -- just put it into your /dev/.htaccess

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

It tells Apache to redirect if:

  • domain is not dev.example.com
  • URL starts with /dev/ (which will only happened if requested via main domain)

When I use that code I should have removed the RedirectMatch from the root, right? If so, adding the code you provided in the dev subfolder didn't do anything. –  Shawn Collier Jul 5 '11 at 20:38
    
@Shawn I have updated my answer with new rules (I edited wrong file when tested these rules myself -- I edited main htaccess instead the one from sub folder). The changes are minimal. –  LazyOne Jul 5 '11 at 20:53
    
Thanks, that worked perfectly. –  Shawn Collier Jul 5 '11 at 20:58

Try this:

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

Doesn't appear to do anything. –  Shawn Collier Jul 5 '11 at 6:58
    
And if you comment the rules that redirect non-www to www? –  Alex Jul 5 '11 at 7:04
    
If not, since you have the non-www to www redirect, try this one: RedirectMatch 301 ^/dev/(.*)$ http://dev.example.com/$1 –  Alex Jul 5 '11 at 7:07
    
That one works, but it causes a URL like http://dev.example.com/ps3/?p=ps3&urltype=slash. Is there something that can be modified in the RedirectMatch or is there some other area of the htaccess file that's affecting things? (I'll be heading to bed in a few minutes, so I won't be able to look at this again till tomorrow morning.) –  Shawn Collier Jul 5 '11 at 7:14

@Shawn Post your whole .htaccess contents here (update your question) -- looks like you have rules in wrong order (RedirectMatch executes after RewriteRules that's why you see real URLs instead of nice one). –  LazyOne Jul 5 '11 at 9:00

I've used the following redirect-code to rewrite any sub-domains to a URL-parameter:

# rewrite subdomain
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{HTTP_HOST} ^([^\.]+)\.example\.org$ [NC]
RewriteRule ^(.*)$ index.php?q=116&company_name=%1$1 [L,QSA,NC]

%1 is the regex-match for the subdomain; $1 consists of all other URL-params;

Play around with it, to redirect to a folder, like:

RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{HTTP_HOST} ^([^\.]+)\.example\.org$ [NC]
RewriteRule ^(.*)$ /%1/$1 [L,QSA,NC]

Maybe it's how my current configuration is, but I got infinite redirect loops whenever I tried using that. –  Shawn Collier Jul 5 '11 at 18:43
