Sensible rewrite-all-to-index for PHP on IIS

web.config

<configuration>
	<system.webServer>
		<rewrite>
			<rules>
				<rule name="SpecificRewrite" stopProcessing="true">
					<match url="^" />
					<conditions>
						<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /> 
					</conditions>
					<action type="Rewrite" url="index.php" />
				</rule>
			</rules>
		</rewrite>
	</system.webServer>
</configuration>

This will redirect host.local/long/winded/url to host.local/index.php but it will leave host.local/img/dog.png untouched because it is a real file
