ASP.Net MVC: Excluding spaces from urls with requestPathInvalidCharacters

In my ASP MVC site on IIS7.5, and have set a long maxUrlLength in order to handle urls longer than 260 characters. For this we also have to turn on relaxedUrlToFileSystemMapping.

So we have this in the web.config:

<httpRuntime enableVersionHeader="false" maxUrlLength="1200" 
  relaxedUrlToFileSystemMapping="true"
  requestPathInvalidCharacters="&lt;,&gt;,&amp;,*,%,:,;,\,?,%" />

A side-efect is that no urls that end with a space and a slash are now valid. e.g. "http://mysite.com/path/to/name /" used to throw a HttpException that we caught and issued a 301 redirect. But now it does not.

Is it possible to make this url behave as before? Can I specify the space character in the requestPathInvalidCharacters list somehow? Putting in requestPathInvalidCharacters=" " has no effect on spaces in urls, and neither does requestPathInvalidCharacters=" ". and requestPathInvalidCharacters="%20" is a configuration error.

Does adding work for a space? – rossisdead Feb 15 '13 at 18:35
Ross: no, it does not. I suspect because they are encoded as %20 before that. – Anthony Feb 17 '13 at 00:00
I ended up here trying to figure out how to set the requestPathInvalidCharacters with chevrons. Unrelated, but thanks anyways! – Jerther Jan 08 '15 at 19:54
