Remove multiple forward slashes in URL

Question

I'm trying to remove unwanted additional forward slashes in my URLs. For example:

"http://www.domain.com//" and "http://www.domain.com///"

should redirect to:

"http://www.domain.com"

I'm using the IIS URL rewrite module. Here is what I have so far:

<rule name="RedirectForwardSlash" stopProcessing="true">
      <match url="//+$" />
      <action type="Redirect" url="default.aspx" appendQueryString="true" redirectType="Permanent" />
</rule>

Answer 1

1. Why remove additional slashes if they are technically correct?
2. How are the multiple slashes even occurring in the first place?
3. What is wrong with your current code? Are there any errors?
