One comment on “Using URL ReWrite to host multiple sites/domains under a single site”

   I set up all three of my alias domains with the following rule:

   <rule name="Alias Domains" patternSyntax="ECMAScript"
   stopProcessing="false">
   <match url="^([^?]*)" />
   <conditions logicalGrouping="MatchAll"
   trackAllCaptures="true">
   <add input="{HTTP_HOST}"
   pattern="killstone|raggedbay|musicalcollective" />
   <add input="{REQUEST_URI}"
   pattern="^killstone|^raggedbay|^musicalcollective"
   negate="true" />
   </conditions>
   <action type="Rewrite" url="{C:0}/{R:0}"
   appendQueryString="true" logRewrittenUrl="true" />
   </rule>

   Then, I added a second rule to handle "pretty permalinks" in my subdomain’s WordPress instances:

   <rule name="Alias WordPress" stopProcessing="true">
   <match url=".*" />
   <conditions logicalGrouping="MatchAll"
   trackAllCaptures="false">
   <add input="{HTTP_HOST}"
   pattern="killstone|raggedbay" />
   <add input="{REQUEST_FILENAME}" matchType="IsFile"
   negate="true" />
   <add input="{REQUEST_FILENAME}" matchType="IsDirectory"
   negate="true" />
   </conditions>
   <action type="Rewrite" url="{C:0}/index.php"
   logRewrittenUrl="true" />
   </rule>

   The only caveat is that the pretty URLs rewrite only works on sub-folders if you use a trailing slash. So, in order to log into the WordPress dashboard, you need to go to /wp-admin/ (not just /wp-admin).
