Rewriting ASP URL and getting Redirect Loop

I have a script in place that replaces example.com/folder/index.php/pagename with example.com/pagename.

But example.com/pagename technically doesn't exist - so if someone navigates to it they get a 404.

I tried to add a redirect in my web.config file that looks like:

<rewrite>
<rules>
<rule name="my redirect" stopProcessing="true">
<match url="pagename" />
<action type="Redirect" url="http://www.example.com/folder/index.php/pagename/" redirectType="permanent" appendQueryString="false" />
</rule>
</rules>
</rewrite>

But it's resulting in a redirect loop. I noticed that if I change the final URL to something different like example.com/pagenamealternate that it works just fine.

Can anyone tell me if there's a handy condition or alternative way of solving this problem?

You are getting a redirect loop because your pattern pagename also matches the target URL, which has pagename in it.

Change your match url to ^pagename$, now the rewrite rule only kicks in for requests with the exact url: example.com/pagename, you may want to allow additional text after the pagename, then use: ^pagename as the match pattern. The ^ in a regular expression means the beginning of a string, this works because the rewrite engine looks at everything after the hostname part.

Also consider a rewrite action rather than a redirect.
