IIS Rewrite Rule for Redirect to Directory

The web hosat I am currently with allows multiple domains, but only 6 websites; this means I have to be a little creative sometimes when creating additional sites.

I actually have a lot more than six websites being hosted on my account, due to a mix of WordPress MU and redirects to folders.

The redirect is done using an IIS rewrite rule. As I may be moving web host soon, I’m posting this so that I have easy access should I need.

This code goes in the rewrite section of the web.config file:

<rewrite>
	<rules>
		<rule name="Rewrite subdomain.azurecurve.co.uk subdomain to dir" enabled="true">
			<match url="^(.*)$" />
			<conditions>
				<add input="{HTTP_HOST}" pattern="^subdomain\.azurecurve\.co\.uk$" />
			</conditions>
			<action type="Rewrite" url="_subdomain.azurecurve.co.uk/{R:1}" />
		</rule>
		<rule name="subdomain.azurecurve* wordpress" patternSyntax="Wildcard">
			<match url="*subdomain.azurecurve*" />
			<conditions>
				<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
				<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
			</conditions>
			<action type="Rewrite" url="_subdomain.azurecurve.co.uk/index.php" />
		</rule>
</rewrite>

The second rule is, I believe, required specifically for redirects for WordPress sites, the majority of which my rewrites are for.
