PHP Script for URL Redirect with parameters

Hello,

I need to redirect all requests to one domain and redirect it to another.  However, I need it to redirect with all the parameters.

I can put a php page on a Netfirms.com domain.

I have a main domain (e.g. www.LongDomainName.com) and a short domain (e.g. www.shrtDm.com).  

I have recently moved my corporate website into a fully hosted environment.  Previously, we hosted the proprietary CMS.  In my setup, I had IIS forward all requests for www.shrtdm.com to www.LongDomainName.com, including all parameters after the domain.

So  IIS would redirect requests for http://www.shrtdm.com/contactus to http://www.LongDomainName.com/contactus.  It was a wildcard redirect, so it would work for any URL, not just predesignated ones, such as:

Redirect request for:

www.shrtDm.com/page.aspx?pid=10321

to:

www.LongDomainName.com/page.aspx?pid=10321


Thank You.

You can use PHP header("Location") to do this redirection.  I'll show you an example as soon as I can find it in my library.

This ought to do it.
<?php

// GET REQUEST URL + VARS
$path = $_SERVER["REQUEST_URI"];

// SET NEW DOMAIN NAME - FULLY QUALIFIED
$name = 'http://www.MyLongDomainName.com';

// CREATE THE NEW URI LOCATION WITH THE NEW DOMAIN + REQUEST DATA
$uri = $name . $path;

header("HTTP/1.1 301 Moved Permanently");
header("Location: $uri");
exit;

I'm new to PHP, I'm guessing that you missed the ?> at the end.

Good point, but no, I deliberately omitted the close-PHP tag.  The ?> at the end is useless and should be avoided if at all possible.  The only permissible use of the close-PHP tag is when the PHP script must stop so HTML can start.  In professionally written PHP applications this happens very, very rarely.

Great.  Thanks.  It works, if I directly request the URL.  ie.  www.shrtdm.com/index.php?pageid=1929

But it doesn't work for other pages, e.g. www.shrtdm.com/index.aspx?pageid=1912.

Any ideas?  I'm thinking that it's more to do with the host setup than anything.

There is a difference between PHP pages and ASPX pages, and this question was only posted in the PHP Zone.  Sorry but I reflexively responded with only the basic PHP solution.  Maybe you can ask the EE moderators to add it to other EE Zones.

Sorry.  According to the page you described, you do deserve an Excellent.  Do you know the best way to change the rating?  Looks like I need to post another request.

You can use "Request Attention" if you want to ask a moderator for assistance. The link is typically near the original question.  Thanks for your consideration.
