// HACK: Fix for WHATWG URL object not parsing non-standard URL schemes like
|
|
// 'udp:'. Just replace it with 'http:' since we only need a few properties.
|
|
//
|
|
// Note: Only affects Chrome and Firefox. Works fine in Node.js, Safari, and
|
|
// Edge.
|
|
//
|
|
// Note: UDP trackers aren't used in the normal browser build, but they are
|
|
// used in a Chrome App build (i.e. by Brave Browser).
|

|
// - Firefox: https://bugzilla.mozilla.org/show_bug.cgi?id=1374505
