It works a bit differently because it does text substitution.  That's a
more general case and is much more common for our needs.  Here's how it
would work in your case:

1.	use a requesttemplate
2.	the URL would be http://w${RANVAR}.example.com/file.html
	RANVAR is the substitution variable, you can pick your
	variable names and have more than one in a URL
3.	create a substitution file containing lines with the text
	you want substituted as (example file name mysubstfile):
	0000\n
	0001\n
	...
	9999\n
4.	Have a config file with a subst_list entry like this

	<subst_list>
		<subst_entry>
			<subst_var>RANVAR</subst_var>
			<subst_file>/path-to/mysubstfile</subst_file>
		<subst_entry>
	<subst_list>


The win is that the subst file can contain lots of things beyond random
numbers.  It's very easy to create a subst file from an access log and
get very good agreement with your actual traffic.  So URLs like
http://example.com/?q=${QUERYFROMREALTRAFFIC} work fine.  You can do
port numbers too.

Very large subst files work fine.
