network/module/Makefile - 1. 310133 - Added nsIRefreshUrl.h to the list of exports. network/module/makefile.win - 1. 310133 - Added nsIRefreshUrl.h to the list of exports. network/module/nsIHttpUrl.h - 1. 310133 - Extended the nsIHttpUrl interface to include the AddMimeHeader() method which adds an http header to the url. network/module/nsHttpUrl.cpp - 310133 - 1. Added support for the AddMimeHeader() method so http urls can have headers added outside of the actual data retrieval in netlib. This method calls NET_ParseMimeHeader() directly. 2. Added a public member, a pointer to the netlib URL_Struct that was created for this nsHttpUrlImpl. This pointer is the link between netlib and the outside world; the adhesive agent between url structs and nsURLImpls. network/module/nsNetStream.h - 1. 310133 - Added a public memeber variable to nsConnectionInfo. It's a bool that tells us whether or not a redirect has occurred. network/module/nsNetStream.cpp - 1. 310133 - Added initialization (FALSE) of new redirect member. network/module/nsNetStubs.cpp - 1. 310133 - Implemented FE_SetRefreshURLTimer(). This function is called from NET_GetURL() when we recognize that we have a url to refresh. network/module/nsStubContext.cpp - 1. 310133 - Added check to see if we're redirecting in stub_complete() which gets called when a stream completes. If we are, we don't want to release/destroy the pConsumer, this will happen in nsNetService's bam_exit_routine(). network/module/nsNetService.cpp - 1. 310133 - added nsConnectionInfo->redirect check in bam_exit_routine() so we give the consumer a successful binding event if the consumer is still around. This is iffy.
