Too many redirects error after defining a redirect in Web.config

Question

I have an ASP.NET MVC (5) application and need to redirect urls such as

<domain>/london to <domain>/locations/london

I've defined a redirect in Web.config in system.Webserver

<rule name="london">
     <match url="london" />
     <action type="Redirect" url="locations/london" />
</rule>

When I run the site locally and browse to localhost:1111/london I get the following error

localhost redirected you too many times. ERR_TOO_MANY_REDIRECTS

What am I doing wrong?

I've spent some time looking online but can't find the answer...

Answer 1

your rule is basically saying if the URL contains London then redirect to locations/London . But locations/London contains the word London too so it will redirect again.

Try setting the rule to be

^london

(start with london)
