In Azure all hosted sites have URL Rewrite and ARR (Application Request Routing) modules installed but the proxy functionality is disabled by default in ARR. So, when you create a simple rewrite rule like the one that follows:
1 2 3 4 5 6 7 8 | <rewrite> <rules> <rule name="ProxyAdmin" stopProcessing="true"> <match url="backend/api(.*)" /> <action type="Rewrite" url="http://api.yourdomain.com/api/{R:1}" logRewrittenUrl="false" /> </rule> </rules> </rewrite> |
where, for example all the requests like http://www.yourdomain.com/backend/api/… should be served by http://api.yourdomain/api/… will result in a 404 (Not Found) status code with the following message:
1 | The resource you are looking for has been removed, had its name changed, or is temporarily unavailable. |
