goog.net.xpc.IframePollingTransport(channel, opt_domHelper)

Iframe polling transport. Uses hidden iframes to transfer data in the fragment identifier of the URL. The peer polls the iframe's location for changes. Unfortunately, in Safari this screws up the history, because Safari doesn't allow to call location.replace() on a window containing a document from a different domain (last version tested: 2.0.4).

channel {goog.net.xpc.CrossPageChannel}
The channel this transport belongs to.
opt_domHelper {goog.dom.DomHelper=}
The dom helper to use for finding the correct window.

.IFRAME_PREFIX {string}

The string used to prefix all iframe names and IDs.
