Hi Experts

We have old urls in google and other locations but have a brand new domain and site structure. We would like to 're-map' the old domain and urls to their new location.

The old domain is setup as a domain alias of the new domain with the hosting company.

Is it possible with htaccess to redirect:

http://olddomain.com/index.php?page=services
to
http://newdomain.com/subfolderA

http://olddomain.com/index.php?page=contact
to
http://newdomain.com/subfolderB

etc


Thanks for your time.

You can probably do this with .htaccess or with PHP.  I think either way you want to send a 301 moved permanently header.  I will try to show you a PHP example of how the design might work.

Here is the PHP example.  If the list of new URLs is very long, I might be more comfortable using the PHP redirection, since it may be easier to keep it organized.  At least that is the way I would think.  You might add a logging statement to this to keep track of the number of times it was necessary to redirect clients.  Then you would have a sense of when the redirection is no longer needed, ie, when everyone has found the new URLs.

This code is completely untested, but valid in principle.
<?php // RAY_temp_hnEE.php
error_reporting(E_ALL);


// MAP OLD DESIGN TO NEW DESIGN LIKE THIS /*
http://olddomain.com/index.php?page=services
to
http://newdomain.com/subfolderA

http://olddomain.com/index.php?page=contact
to
http://newdomain.com/subfolderB
*/


// YOU MAY WANT THIS OR NOT - NOT SURE
session_start();

// AN ARRAY TO ORGANIZE THE PAGE NAMES AND THE FOLDERS
$map = array
( 'services' => 'subfolderA'
, 'contact'  => 'subfolderB'
)
;

// ASSUMPTION: WE DO NOT KNOW WHERE TO GO
$url = NULL;

// IS THE REQUEST PRESENT AND WELL-FORMED?
$page = isset($_GET['page]) ? strtolower(trim($_GET['page'])) : NULL;
if ($page)
{
    // IS IT A REQUEST FOR A PAGE WE KNOW ABOUT?
    if (array_key_exists($page, $map))
    {
        // SET THE DESTINATION PAGE
        $url 
        = 'http://newdomain.com' 
        . DIRECTORY_SEPARATOR 
        . $map[$page]
        ;
    }
}

// IF WE KNOW WHERE TO GO
if ($url)
{
    header("HTTP/1.1 301 Moved Permanently"); 
    header("Location: $url"); 
    exit;
}

// HANDLE THE 404 NOT FOUND CONDITION HERE...

Sorry -- I just assumed since this question was in the PHP zone that you were open to a PHP solution.  Maybe one of the other experts will give you the .htaccess version.  

Best of luck with it, ~Ray

here you go

      RewriteEngine on
      RewriteCond %{HTTP_HOST} ^www.olddomain.com$ [NC]
      RewriteCond %{QUERY_STRING} ^page=services$
      RewriteRule ^index\.php$ http://www.newdomain.com/subfolderA? [R=301,L]

      RewriteCond %{HTTP_HOST} ^www.olddomain.com$ [NC]
      RewriteCond %{QUERY_STRING} ^page=contact$
      RewriteRule ^index\.php$ http://www.newdomain.com/subfolderB? [R=301,L]


Hope the above helps

HI babuno5

Thanks for that - perfect!

What should we do though if they come to the homepage:

http://olddomain.com/
to
http://newdomain.com/

I had a go at working this out but it cancels out your other work from above.

Thanks.

Try this after the previous lines by babuno5:

      RewriteCond %{HTTP_HOST} ^www.olddomain.com$ [NC]
      RewriteRule ^/(.+) http://www.newdomain.com/ [R=301,L]

Since the other rules have an L, they should be processed as the last rule, if matched. So only those that didn't match will get this new rule.
