You got this error because there are too many URL segments in the request.

Check this: http://www.iis.net/learn/extensions/introduction-to-iis-express/iis-80-express-readme
IIS 8.0 Express returns an HTTP 404.20 error for Too Many URL Segments.

UPDATE:

Follow the site below to change the limit of URL segments count.(The default value is 32.)

After changing the configuration, the url will pass the validation of segments count.

Now error will throw about exceeding the maxUrlLength.

You need to add following content to the <system.web /> section of your Web.config file.

<httpRuntime maxUrlLength="9999" maxQueryStringLength="9999" />

Then your long request url with many segments works finally!!!
