    Url Rewrite .htm to extensionless, but ignore umbraco directories

    I need to redirect all of the legacy .htm urls for my website to extensionless urls, so:

    http://www.website.com/page.htm  -->  http://www.website.com/page

    I created the following rule in config/UrlRewriting.config, but which fixed the above issue, but created an issue where all of the backoffice paths are returning 404:

    <add name="HtmToExtensionless"
     redirect="Domain"
     ignoreCase="true" 
     rewriteUrlParameter="IncludeQueryStringForRewrite"
     virtualUrl="http://www.website.com/(.*)(\.htm)"
     redirectMode="Permanent"
     destinationUrl="http://www.website.com/$1" />

    So requests like these are returning 404:

    http://www.website.com/umbraco/views/components/application/umb-navigationl?umb__rnd=7.4.2.1536555776

    I'm pretty sure my problem is with my regex, but I'm not sure. Anyone care to advise?

    Turns out I was being a dufus. Umbraco actually requests resources that have .html extensions, and my regex was grabbing those and stripping the .htm from them. Just had to check for the beginning and end of the string, and now we're golden:

    <add name="HtmToExtensionless"
     redirect="Domain"
     ignoreCase="true" 
     rewriteUrlParameter="IncludeQueryStringForRewrite"
     virtualUrl="^http://www.website.com/(.*)(\.htm)$"
     redirectMode="Permanent"
     destinationUrl="http://www.website.com/$1" />

    Glad you figured it out. For future reference, you can also use a negative lookahead to ignore particular paths (e.g., Umbraco):

    <add name="HtmToExtensionless"
     redirect="Domain"
     ignoreCase="true" 
     rewriteUrlParameter="IncludeQueryStringForRewrite"
     virtualUrl="^http://www.website.com/(?!umbraco/)(.*)(\.htm)$"
     redirectMode="Permanent"
     destinationUrl="http://www.website.com/$1" />

    Thanks for the tip Nicholas. One of these days I need to sit down and actually put some effort into memorizing regex syntax :)
