Unless you use some client-side scripting, a form will always submit to
just one place.

However, that one place could be a script that looks at the form
submission and sends an HTTP 301 redirect to various different places
based on the form contents.

Here's some example code:

<form action="redirect.php" method="get">
<fieldset>
<legend>enter a name</legend>
<input name="name">
<input type="submit">
</fieldset>
</form>

<?php
// This file is "redirect.php".

// What is my domain name?
$mydomain = 'example.com';

// You used 'exampledomain.com' -- you might not have known
// that there exists a domain 'example.com' which is specially
// reserved just for examples.

// What name has the user entered?
$name = $_GET['name'];

// Convert down to lower case
$name = StrToLower($name);

// Remove all characters except 0-9 and a-z
$name = pReg_Replace('/[^0-9a-z]/', '', $name);

// Generate Final URL
$url = "http://{%s}.{$mydomain}/";

// Redirect
Header("HTTP/1.1 301 Redirect");
Header("Location: {$url}");
?>
