Question

I want to remove trailing dots such as ... from all urls on IIS. I tried to use the following rule:

<rule name="RemoveTrailingDots" stopProcessing="true">
  <match url="^([^.]*)\.+$" />
  <action type="Redirect" redirectType="Permanent" url="{R:1}" />
</rule>

This works as expected on my local PC but not on my website.

For example I expected /fruits/apple... to be redirected to /fruits/apple but no redirect happens.

Thanks

Your problem is you’re requiring that everything before the trailing dots be completely devoid of dots. You might try something like

<match url="^(.*[^.])\.+$" />

This will match any number of characters, followed by a single non-dot character (as part of the capture), followed by dots (which aren’t captured).

That said, I don’t understand why you even want this. URLs with trailing dots are not even remotely a common thing to have.
