+// handles multipart/x-mixed-replace data.  We special case
+// multipart/x-mixed-replace because WebCore expects a separate
+// didReceiveResponse for each new message part.
+//
+// Most of the logic and edge case handling are based on the Mozilla's
+// implementation in netwerk/streamconv/converters/nsMultiMixedConv.cpp.
