310133 - 1. added LoadURLOnTimer() and CancelLoadURLTimer() implementations to the nsDocLoaderImpl class.
2. Changed nsDocumentBindInfo class to support the nsIRefreshUrl interface.
3. Changed the nsDocumentBindInfo contructor to set the m_ExtraInfo variable to the aExtraInfo pointer passed in. This must have been an oversight on the part of the original implementor.
4. Added a simple data placeholder class to hold the data that will be used to load the url on the timer.
webshell/src/nsWebShell.cpp -
1. 310133 - When the webshell is destructed or about to load a new url, the loader now calls CancelLoadURLTimer() which cancels and releases the timers.
