This has been bugging me …
IE7 always bypasses the proxy when connecting to localhost, irrelevant of what options you choose. This makes life painful if you’re trying to use some like Fiddler when developing a site locally.
Unfortunately we don’t have this flexibility with Casini (the one included with VS 2005) as it only accepts connections to http://localhost:xyz/.
Use http://localhost.:xyz/ (notice the added period between the hostname and the colon).
- IE7 is no longer sure if it’s local or not, so we get the proxy,
- it still gets routed correctly, and
- Casini still accepts the connection.
