How to do a rewrite rule in web.config

If you would like to do a domain URL redirection from to or vise versa, you can do something like this:

Place either of these (depending on what you’d like done. And edit to match your domain) inside the <system.webServer></system.webServer> tags in the web.config of the domain.

<rule name=”Add WWW prefix” >
  <match url=”(.*)” ignoreCase=”true” />
      <add input=”{HTTP_HOST}” pattern=”^domain\.com” />
  <action type=”Redirect” url=”{R:1}”
    redirectType=”Permanent” />

<rule name=”Remove WWW prefix” >
  <match url=”(.*)” ignoreCase=”true” />
      <add input=”{HTTP_HOST}” pattern=”^www\.domain\.com” />
  <action type=”Redirect” url=”{R:1}”
    redirectType=”Permanent” />

  2. Hi,

    I would like to use this method to point different domains to different folders on my site, because I’m using HelpConsole as my website editing application. HelpConsole resides in /wwwroot and creates websites in subfolders. What would the code look like?

    If the domain is, then go to the systemic (/wwwroot/systemic) folder;

    Thanks very much!
