- Add a dot after “localhost”, so it becomes http://localhost.
- This does not always work. On my Windows Server 2008 R2 box, it does not.
- Access your web using the (netbios) machine name.
- Access your web through the fiddler proxy: http://ipv4.fiddler/AppName…
- Run your web’s application pool under the same account that fiddler is running under, ie. the account you are logged on as.
- NB! This also has the MAJOR benefit that you will see web service calls from your website.
- IIS Express by default runs as the logged on user, so Fiddler will capture traffic.
