Subdomain redirect scripts

**NexDog** · 04-07-2004, 09:34 AM

The new Plesk 7 has real subdomain support so we would like to encourage everyone (especially those with multi-domain accounts) to use subdomains even with redirects. Using the old system, you would create a subdomain just like a norrmal domain and if you wanted a redirect, you'd choose the Standard Forward or Frame Forward option under Setup.

You can achieve this with the new subdomain system as well. To create a subdomain as a standard forward, the quickest way to achieve this is with PHP. You can quickly create your subdomain in Plesk and then go into the file manager, go into subdomains, click on your new subdomain and then httpdocs. Create a file called index.php and enter this code (replacing the URL for whatever you will need):

Code:

<?php
header("Location: http://www.domain.com/subdirectory");
exit;
?>

Here is an example:

http://hostnexus.control-access.com/

To get the popular Frame Forward affect, you simply need to make a file called index.html and enter this code:

Code:

<HTML> 
<HEAD> 
<TITLE>TITLE GOES HERE</TITLE>
</HEAD> 

<FRAMESET COLS="100%"> 
  <FRAMESET ROWS="100%"> 
    <FRAME SRC="http://domain.com"> 
  </FRAMESET>
</FRAMESET> 
</HTML>

(Many thanks to RobbieLePommie for that code)

And here is an example:

http://hn.control-access.com/

So if you have subdomains, please try and convert them to this new system as it will have a possible affect on apache restart times.

Quick question- if we delete the top domain and create the subdomain as you noted, will there be any delays in it working (dns), or will it be live right away?

It will be live before you get a chance to launch a browser (or pretty quick anyway

).

I tried
http://hostnexus.control-access.com/ and I only get a blank page:

I do see this code when looking at source code:

<?php
header("Location: http://www.hostnexus.com");
exit;
?>

Looks fine to me. Any Idea why this happens?

hn.control-access.com frame redirect works perfectly though.

I've been using these in html pages (example http://www.lansberry.net )

PHP Code:


			
        <meta http-equiv="refresh" content="0;URL=http://www.middleground.us">

and

PHP Code:


			
    <body onload="window.location.href=http://www.middleground.us">

may not be the quickest, but works across browsers and OS's

Using a meta-refresh and setting it to 0 can get you bounced by some search engines.

**NexDog** · 04-08-2004, 03:15 AM

Hmmm, no idea what happened to http://hostnexus.control-access.com/ as it was working fine before. I must have done something stupid and the answer must be staring me in the face....testing....

If you have a redirect in htaccess they generally only index the redirected site. That's my experience with the www.domain.com and domain.com, anyway. It makes sense they would do this for a META refresh as well; after all most META refreshes exist to say "My site has now moved, taking you there now..."

Anyhow, I simply forgot to check off PHP support for the subdomain. This works:

http://hostnexus.control-access.com/

Look how fast it it is. I reckon it's faster than .htacess and definitely alot faster than meta-refresh or JS.

I wrote an automated version of the first PHP script. This will automatically turn 'sub.example.com/page.php?a=test' into 'example.com/sub/page.php?a=test' Just copy and paste the following code.

PHP Code:


			
<?php

    $domain = $_SERVER['SERVER_NAME'];

    $data = $_SERVER['REQUEST_URI'];

    

    if(fnmatch('*.*.*',$domain)) {

        $domain = explode('.',$domain);

        $newDomain = $domain[1].'.'.$domain[2].'/'.$domain[0].$data;

        

        header('Location: '.$newDomain);

    } else {

        echo 'Could not forward from this URL.';

    }

?>

Hope that helps

Note: This does not support TLDs such as '.co.uk', '.com.cn', or any TLDs with two parts.
