How to get Fiddler to filter specific localhost ports

Question

In a reverse of the usual request of how do I get Fiddler to capture requests to localhost, how do I stop it getting specific ports?

Since installing the IE 9 RC, I'm getting loads of requests to Mesh appearing ...

http://localhost:2048/V4.0i/Sync/Devices/SDI6BHE6YYAHMR67S32S4MTROU/Endpoints

I've tried adding locahost:2048 to the Fiddler Filters / Hide the following Hosts, but that's not working

Answer 1

Sussed it ... in Fiddler, open the custom rules with Ctrl+R and add to the OnBeforeRequest ...

if (oSession.host=="localhost:2048"){
    oSession["ui-hide"] = "true";
}
