An example web.config with the correct settings is below.

Note the security section which disables some paranoid protection IIS has switched on by default. If your server doesn’t allow double escaping of request strings, the YOURLS links with a + in them don’t work. This breaks the admin interface and the stats reporting pages.

The rest of the web.config is standard stuff to fix a non-canonical hostname, and make sure the IDs are rewritten to the right pages:

<system.webServer>
	<security>
		<requestFiltering allowDoubleEscaping="true" />
	</security>
	<rewrite>
	<rules>
		<rule name="Canonical Host Name" stopProcessing="true">
			<match url="(.*)" />
			<conditions>
				<add input="{HTTP_HOST}" negate="true" pattern="^domain\.com$" />
			</conditions>
			<action type="Redirect" url="http://domain.com/{R:1}" redirectType="Permanent" />
		</rule>
		<rule name="YOURLS 1" stopProcessing="true">
			<match url="^([0-9A-Za-z]+)/?$" ignoreCase="false" />
			<conditions logicalGrouping="MatchAll">
				<add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" negate="true" />
				<add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" negate="true" />
			</conditions>
			<action type="Rewrite" url="/yourls-go.php?id={R:1}" appendQueryString="false" />
		</rule>
		<rule name="YOURLS 2" stopProcessing="true">
			<match url="^([0-9A-Za-z]+)\+/?$" ignoreCase="false" />
			<action type="Rewrite" url="/yourls-infos.php?id={R:1}" appendQueryString="false" />
		</rule>
		<rule name="YOURLS 3" stopProcessing="true">
			<match url="^([0-9A-Za-z]+)\+all/?$" ignoreCase="false" />
			<action type="Rewrite" url="/yourls-infos.php?id={R:1}&amp;all=1" appendQueryString="false" />
		</rule>
	</rules>
	</rewrite>
</system.webServer>

Since this involved a move to a Windows box away from UNIX hosting, I had to configure in IIS7 some of the settings I had in the .htaccess under the UNIX host.

For example, I want a canonical host name (so visitors always see workavoidance.net with no www prefix in the address bar) and to ensure that the WordPress permalinks work properly. While I was at it I took the opportunity to disable hot-linking of our images, since for some reason a Russian website had taken a shine to some of our Armory graphics.

Below is the web.config I created. It redirects users to the canonical host name, enables WordPress permalinks and disables hot-linking of our images. The redirect proved something of a problem to begin with. Our iPhone App “Monkey Shaker” has an online high score system. Scores are submitted from the app via an encrypted HTTP POST to a PHP page which decrypts the information and updates the database. I discovered that when you issue a server side redirect most clients won’t re-POST their data to the new page – they will issue a GET for the new page and the original POST data is lost. This meant that highscore submissions were failing.

(NB: this isn’t as big a disaster as it sounds since we built a very robust mechanism to retry score submission into the app.)

So, you’ll note an extra entry in the web.config to exclude that page from a redirect:

<add input="{URL}" negate="true" pattern="scoresubmit\.php$" />

“Why not just change the URL in the app to be canonical?!” You may well ask. Yes, we probably will, but that relies on issuing an update and getting over a quarter of a million users to download it. This way we don’t have to rely on that.

Still to come – how I implemented caching in WordPress and in our high score system to improve performance.

Here’s the rewrite rules section of the completed web.config:

<rule name="Canonical Host Name" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTP_HOST}" negate="true" pattern="^workavoidance\.net$" />
<add input="{URL}" negate="true" pattern="scoresubmit\.php$" />
</conditions>
<action type="Redirect" url="http://workavoidance.net/{R:1}" redirectType="Permanent" />
</rule>
 
<rule name="Prevent image hotlinking">
<match url=".*\.(gif|jpg|png)$"/>
<conditions>
<add input="{HTTP_REFERER}" pattern="^$" negate="true" />
<add input="{HTTP_REFERER}" pattern="^http://workavoidance\.net/.*$" negate="true" />
</conditions>
<action type="Rewrite" url="/no.png" />
</rule>
 
<rule name="wordpress" patternSyntax="Wildcard">
<match url="*" />
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="index.php" />
</rule>
