Restart marker reply. In this case, the text is exact and not left to the particular implementation; it must read: MARK yyyy = mmmm where yyyy is User-process data stream marker, and mmmm server's equivalent marker (note the spaces between markers and "="). 重新啟動標志回應。這種情況下，信息是精確的并且不用特別的處理；可以這樣看：標記 yyyy = mmm 中 yyyy是用戶進程數據流標記，mmmm是服務器端相應的標記（注意在標記和等號間的空格）。
