Question

I am working on a protocol handler for Firefox and I call the resource like that:

var ioservice = Cc["@mozilla.org/network/io-service;1"]
                    .getService(Ci.nsIIOService);
var uri = ioservice.newURI('http://someurl'+someparams, null, null);

The question is that I want the user to see my protocol handler – like protocol:params instead of the real URL.

Answer 1

The problem is that your nsIProtocolHandler.newChannel() implementation returns a regular HTTP channel – and it is associated with an HTTP URL rather than yours. This is easy to fix however, set channel.originalURI to your URL (the one your got as parameter to newChannel()).
