Fiddler removed session contains url

1. Add a tag for url contains something in OnBeforeResponse

if(oSession.uriContains("abc/abc.html")){

oSession.oResponse["tag"] = "mock";

}

2. Add a case in OnExecAction

case "removetag":

if (sParams.Length<2) { FiddlerObject.StatusText="Please specify url part to wipe."; return;}

FiddlerObject.UI.actSelectSessionsWithResponseHeaderValue("tag", sParams[1]);

FiddlerObject.UI.actRemoveSelectedSessions();

FiddlerObject.UI.lvSessions.SelectedItems.Clear();

FiddlerObject.StatusText="Removed url contains: " + sParams[1];

break;

Then, ALT+Q in fiddler 

type removetag mock, then all the url contains abc/abc.html will be removed.

For keep sessions contains url is very similar 

case "keeptag":

if (sParams.Length<2) { FiddlerObject.StatusText="Please specify url to retain during wipe."; return;}

FiddlerObject.UI.actSelectSessionsWithResponseHeaderValue("tag", sParams[1]);

FiddlerObject.UI.actRemoveUnselectedSessions();

FiddlerObject.UI.lvSessions.SelectedItems.Clear();

FiddlerObject.StatusText="Removed all but URL contains: " + sParams[1];

break;

For filter out something other than url, you can do in the same way.

Please make sure your new added http header doesn't break your stuff.
