Some folks have indicated that they PREFER that loopback traffic not appear in the session list, usually due to noise from Windows Live Mesh or other similar tools.

You can filter out loopback traffic using Fiddler's Filters tab; simply put localhost into the "Hide the following Hosts" box. Alternatively, if you want to prevent loopback traffic from going to Fiddler at all, click Tools > Fiddler Options > Connections. In the box at the bottom right, remove any <-loopback> token and instead add a <loopback> token. That token has no meaning to WinINET, but it tells Fiddler not to put the <-loopback> token in when it registers as the system proxy.

@Fabio: I don't really understand what "unfortunately it breaks" means. The browser requires that the server return a MIME-type of "text/css" and will not apply a stylesheet with a different MIME-type (except same-origin and only in legacy modes) so suggesting that some other type might be accepted would be inaccurate.

Any chances "text/css" will have "*/*;q=0.1" at the end?

(unfortunately it breaks some script generated content - other browsers have it)

@Viller: Internet Explorer supports a wide variety of image and script formats beyond those listed, hence the */* at the end. Trying to be specific about "every supported image format" suffers from the same functionality and performance problems I mentioned in my original "Vary with Care" article.

Why "*/*" for images and scripts? And why "image/*" instead of mentioning every supported image format?
