WordPress Networks - IIS Rewrite Rules on Azure App Service

This is a bit of an extension to my previous post.

One of the last blogs I moved was a MU or a multi-user WordPress blog, which is now known as a Network. This turned out to be a bit more challenging than the single WP blogs. To setup a new instance, these instructions should mostly do the trick however, based on my testing you'll still need the rewrite rules below.

From this post and this post, I was able to assemble the following rewrite rules that have worked for my WPMU blog running on the Azure App Services (as of Sept. 13, 2016)! Don't miss the <httpRedirect enabled="false" ....> line at the bottom - that was very important. You'll also need those MU settings out of your wp-config.php file too.

web.config:

    <system.webServer>
        <rewrite>
            <rules>
                <rule name="WordPress Rule 1" stopProcessing="true">
                    <match url="^index\.php$" ignoreCase="false" />
                    <action type="None" />
                </rule>
                <rule name="WordPress Rule 2" stopProcessing="true">
                    <match url="^([_0-9a-zA-Z-]+/)?files/(.+)" ignoreCase="false" />
                    <action type="Rewrite" url="wp-includes/ms-files.php?file={R:2}" appendQueryString="false" />
                </rule>
                <rule name="WordPress Rule 3" stopProcessing="true">
                    <match url="^([_0-9a-zA-Z-]+/)?wp-admin$" ignoreCase="false" />
                    <action type="Redirect" url="{R:1}wp-admin/" redirectType="Permanent" />
                </rule>
                <rule name="WordPress Rule 4" stopProcessing="true">
                    <match url="^" ignoreCase="false" />
                    <conditions logicalGrouping="MatchAny">
                        <add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" />
                        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" />
                    </conditions>
                    <action type="None" />
                </rule>
                <rule name="WordPress Rule 5" stopProcessing="true">

                    <conditions logicalGrouping="MatchAny">
                        <add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" />
                        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" />
                        <add input="{URL}" pattern="([a-zA-Z0-9\./_-]+)\.axd" />
                    </conditions>
                    <action type="None" />
                </rule>
                <rule name="WordPress Rule 6" stopProcessing="true">
                    <match url="^[_0-9a-zA-Z-]+/(wp-(content|admin|includes)?.*)" ignoreCase="false" />
                    <action type="Rewrite" url="{R:1}" />
                </rule>
                <rule name="WordPress Rule 7" stopProcessing="true">
                    <match url="." ignoreCase="false" />
                    <action type="Rewrite" url="index.php" />
                </rule>
            </rules>
        </rewrite>
        <httpRedirect enabled="false" destination="http://www.examplesite.com" />
    </system.webServer>
