What is the magic behind that DOT which makes Fiddler work?

It took me a while to learn that I have to put a dot after the "localhost" in the URL so that I can use fiddler with my development server.

Why do I need to put this dot here to make fiddler work for my local:

http://localhost.:1888/MyPage.aspx

What does it stand for?

thanks

It's not that you're making fiddler work, but you're making Internet Explorer work. Internet Explorer is written specifically to bypass the proxy server for "localhost" . By attaching a trailing dot, you're providing a valid DNS name that does not match the mechanism within IE that checks the domain (IE does a stricmp(userdata, "localhost") or equivalant).

localhost. just makes the hostname visible to Fiddler; otherwise, IE bypasses proxies.

You can also substitute "ipv4.fiddler" for "localhost" -- which can help prevent confusion, since the dot is easy to miss.
