URL rewriting instructions for IIS

Instructions for IIS 7

Similar to Apache, IIS 7 will pick up the rewrite rules from a file located in the Wheels installation. In the case of IIS 7, the rules are picked up by adding the following web.config file.

This requires that the URL Rewrite Module is installed. It's an IIS extension from Microsoft that you can download for free.

<?xml version="1.0" encoding="UTF-8"?>
                <rule name="ColdFusion on Wheels URL Rewriting" enabled="true">
                    <match url="^(.*)$" ignoreCase="true" />
                    <conditions logicalGrouping="MatchAll">
                        <add input="{SCRIPT_NAME}" negate="true" pattern="^/(flex2gateway|jrunscripts|cf_scripts|cfide|CFFileServlet|cfformgateway|lucee|files|images|javascripts|miscellaneous|stylesheets|wheels/public/assets|robots.txt|favicon.ico|sitemap.xml|rewrite.cfm)($|/.*$)" />
                    <action type="Rewrite" url="/rewrite.cfm/{R:1}" />


Missing Lucee Assets?

If you had an issue with missing lucee CSS files, try changing {SCRIPT_NAME} to {PATH_INFO} in the code above, as this reportedly can resolve the issue

Instructions for IIS 6



Please note that IIS6 was official End of Life as of 2015. These notes are included for historical purposes only.

Unfortunately, there is no built-in URL rewriting mechanism in IIS 6, so getting Wheels working with pretty URLs is a little more complicated than with Apache and IIS 7 (which often comes with the official "URL Rewrite Module" installed by default). Here's what you need to do:

  • Download Ionic's ISAPI Rewrite Filter. NOTE: the version must be v1.2.16 or later.
  • Unzip the file, get the IsapiRewrite4.dll file from the lib folder and put it in the root of your website. (It needs to be in the same folder as the IsapiRewrite4.ini file.)
  • To enable the rewrite filter in IIS 6, click on Properties for your website, then go to the ISAPI Filters tab and click the Add... button.
  • Type in anything you want as the Filter Name and point the Executable to the IsapiRewrite4.dll file.
  • Uncomment the rewrite rules in the IsapiRewrite4.ini file.

NOTE: Make sure you have "Verify that file exists" disabled for your site.

  • Right click your website and select Properties.
  • Click Home Directory tab.
  • Click the Configuration button.
  • Under the Wildcard application mapping section, double-click path for the jrun_iis6_wildcard.dll.
  • Uncheck Verify that file exists.
  • Click OK until all property screens are closed.
