Redirecting to a Sub-Domain

[iPlox]

I have a wordpress based website originally at some domain abc.com which i want to move to a subdomain abc.xyz.com . I have already set up a mirror at abc.xyz.com so I wanted to know if there was a way to redirect (301) every page on abc.com to the corresponding page on abc.xyz.com ?

Thanks,
Abhinav

you have 2 choices, or you do with mod_rewrite from apache or you can eventually use php.

put this on a index page on your "abc.com" ( index.php )

<?php
// sets the new domain
$new_domain= "http://www.google.com/";

// gets the corrent requested url
$old_url = $_SERVER['REQUEST_URI'];

// the redirect part
header("Location: $new_domain.$old_url");

 ?>

i'm assuming that the url's are the same and only the domain is diferent, that's what i understand from your message.

hope this helps ( if you wanna try it go to http://www.egek.com/teste/ and it will redirect you to http://www.google.com/teste/ )

That's a great help, thanks. I was wondering if something could do:

abc.com/blabla/whateverhere

to

abc.xyz.com/blabla/whateverhere

?

 

[JFS]

that code does that...

just change the
$new_domain= "http://www.google.com/";
to
$new_domain= "http://abc.xyz.com/";


and

abc.com/anything_here
will go to
abc.xyz.com/anything_here

Ok, excellent, I didnt notice that alteration in the last line. Thanks a lot!!

Just one last question, can this be modified to do a 301 permanant redirect, or does it already do so?

 

[JFS]

301 is via htaccess, i don't know how to do it, maybe someone else can help you with that.

I would have suggested an all .htaccess approach (mod_rewrite), however since you seem to have settled into php already

You can use the header functions to modify headers sent, i.e. you can achieve the same effect as a 301 redirect using it.

header('HTTP/1.1 301 Moved Permanently');

So your code becomes...

<?php
header('HTTP/1.1 301 Moved Permanently');

$new_domain= "http://abz.xzy.com/";
$old_url = $_SERVER['REQUEST_URI'];

header('Location: ' . $new_domain . $old_url);
?>

My, arguably better answer to this would be: (in .htaccess)

RewriteEngine On
RewriteRule ^(.*)$ http://abc.xyz.com/$1 [R=301,L]

yes, agreed, via htaccess is better, but since i'm not very confortable at it i gave a quick answer.
