Subdomain Routing with .htaccess

[charlesg]

I had my server company setup wild card subdomains, so anything.mysite.com will work and display the same content as www.mysite.com.

 

Now I need some .htaccess magic setup to route any sub domain to the www.mysite.com (and all URI segments), but keep the subdomain in the location bar.

 

Unfortunately, I'm not a regex guru.  Does anyone know how to do this who is willing to help me out please?

 

Examples - I need all of these formats to work like this...

 

hello.mysite.com -> www.mysite.com, but display hello.mysite.com

hello.mysite.com/cool/site -> www.mysite.com/hello/site, but display hello.mysite.com/cool/site

hello.again.mysite.com -> www.mysite.com, but display hello.again.mysite.com

hello.again.mysite.com/cool/site -> www.mysite.com/cool/site, but display hello.again.mysite.com/cool/site

Well, i'm not an expert. but this might help you out.

 

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

Thanks, but it didn't do it.  It just routes double subdomains (a.b.domain.com) to the primary domain and changes the url

I found this on a forum thread, but it didn't seem to work either.  Anyone else got an idea?

 

RewriteCond %{ENV:REDIRECT_SUBDOMAIN} ="" 
RewriteCond %{HTTP_HOST} ^([a-z0-9][-a-z0-9]+)\.domain\.com\.?(:80)?$ [NC] 
RewriteCond %{DOCUMENT_ROOT}/%1 -d 
RewriteRule ^(.*) %1/$1 [E=SUBDOMAIN:%1,L] 
RewriteRule ^ - [E=SUBDOMAIN:%{ENV:REDIRECT_SUBDOMAIN},L]

It's a bandaid fix but I use it to separate layout from content in my website. My .htaccess routes all http errors to a particular script. This script displays either the requested webpage or a custom error message. It works because the URI_REQUEST... HTTP_REQUEST... can't remember the name of it atm but that value is still in the $_SERVER array after .htaccess reroutes the request to your script.

 

For example...

• someone types/clicks a link with http://www.mydomain.com/somelink.php
  
• 404 error is generated and redirected
  
• script looks at $_SERVER variable and parses request
  
• if file exists it is included, if not 404 error page displayed
  

 

This URL in the browser will be whatever the user typed or the HREF value.

Here's the beginning of the code from my "master" page:

 

$end = strrpos($_SERVER['REQUEST_URI'],'.');
$page = $_SERVER['DOCUMENT_ROOT'].substr($_SERVER['REQUEST_URI'],0,$end).'.iphp';
if(file_exists($page)) {
	header("HTTP/1.x 200 OK\r\n");
	$require = true;
}

 

If you don't do the header you'll send out the 404 error as a response. And when using header() remember NO OUTPUT whatsoever before it's call.....not even a newline. You just have to modify it to parse it to your needs.... mine are pretty simple as you can see.
