Adding a rule to my htaccess subdomain rewrite

Question

I recently had some help from icyrock.com with a htaccess rewrite that sends all subdomain requests to domain.com/apps

You can find the thread here and the code is here:

RewriteBase / RewriteEngine On #### URL Rewrite Handler for Subdomains (by Randall Krause) #### RewriteCond %{ENV:REDIRECT_SUBDOMAIN} ="" RewriteCond %{HTTP_HOST} ^([a-z0-9][-a-z0-9]+)\.domain\.com\.?(:80)?$ [NC] RewriteCond %{DOCUMENT_ROOT}/apps/%1 -d RewriteRule ^(.*) apps/%1/$1 [E=SUBDOMAIN:%1,L] RewriteRule ^ - [E=SUBDOMAIN:%{ENV:REDIRECT_SUBDOMAIN},L] 

As I said this works really well, but I need to add two more rules that I am having trouble integrating without conflicting with the above code.

1. For any requests that are NOT for subdomains I need the main website URL (http://domain.com) to rewrite to http: // www.domain.com
2. For any requests that are NOT for the subdomains I also need to rewrite the URLS to remove an index.php from the URL.

The code for this is:

RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?/$1 [L] 

Adding this in its current form BEFORE the subdomain rewrite rule breaks it.

The only solution I have found is to explicitly define which files are not to be covered by the above rule by doing something like this:

RewriteCond $1 !^(index\.php|images|robots\.txt) 

Does anyone have any ideas?

Thanks,

Tim

Haven't tested it, but try something along these lines (you might need to tweak it):

RewriteCond %{HTTP_HOST} ^domain\.com(:80)?$ [NC] RewriteRule ^(.*)(?:index.php)?$ http://www.domain.com/$1 [R=permanent,L] 

Put the code after RewriteEngine On (i.e. before your first RewriteCond). Note that it's going to remove all index.php endings (i.e. domain.com/a/b/c/index.php will become www.domain.com/a/b/c/. Taken from here:

I suggest you do some reading on mod_rewrite, such as:

• http://httpd.apache.org/docs/2.0/misc/rewriteguide.html
• http://www.askapache.com/htaccess/mod_rewrite-tips-and-tricks.html

if you are going to need it every second day - pays off... :)
