Why is my QUERY_STRING empty?
===

I am running a server locally. It's Apache2 with PHP. Following are the files that I have written.

`.htaccess`
<pre>
ErrorDocument 404 /notFoundError.php

</pre>

`/notFoundError.php`
<pre>
&lt;?php
  echo phpinfo();
?&gt;
</pre>

When I type some non-existing url `http://localhost/this/is/dummy?key=value`, it successfully redirects to `notFoundError.php` and prints the phpinfo table. There I do not find `key=value` in the `_SERVER["QUERY_STRING"]` row.
