Dots in URL causes 404 with ASP.NET mvc and IIS

322

I have a project that requires my URLs have dots in the path. For example I may have a URL such as www.example.com/people/michael.phelps

URLs with the dot generate a 404. My routing is fine. If I pass in michaelphelps, without the dot, then everything works. If I add the dot I get a 404 error. The sample site is running on Windows 7 with IIS8 Express. URLScan is not running.

I tried adding the following to my web.config:

<security>
  <requestFiltering allowDoubleEscaping="true"/>
</security>

Unfortunately that didn't make a difference. I just receive a 404.0 Not Found error.

This is a MVC4 project but I don't think that's relevant. My routing works fine and the parameters I expect are there, until they include a dot.

What do I need to configure so I can have dots in my URL?

Just add this section to Web.config, and all requests to the route/{*pathInfo} will be handled by the specified handler, even when there are dots in pathInfo. (taken from ServiceStack MVC Host Web.config example and this answer https://stackoverflow.com/a/12151501/801189)

This should work for both IIS 6 & 7. You could assign specific handlers to different paths after the 'route' by modifying path="*" in 'add' elements

  <location path="route">
    <system.web>
      <httpHandlers>
        <add path="*" type="System.Web.Handlers.TransferRequestHandler" verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" />
      </httpHandlers>
    </system.web>
    <!-- Required for IIS 7.0 -->
    <system.webServer>
      <modules runAllManagedModulesForAllRequests="true" />
      <validation validateIntegratedModeConfiguration="false" />
      <handlers>
        <add name="ApiURIs-ISAPI-Integrated-4.0" path="*" type="System.Web.Handlers.TransferRequestHandler" verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" preCondition="integratedMode,runtimeVersionv4.0" />
      </handlers>
    </system.webServer>
  </location>
