--- Comment #8 from Misha Koshelev mk144210@bcm.tmc.edu 2007-08-29 00:51:31 --- Oops, please scratch my last comment, it is incorrect.
I just tested and apparently an InternetCloseHandle on just the handle returned by InternetConnect (not calling the one on HttpSendRequest at all) sends the appropriate INTERNET_STATUS_HANDLE_CLOSING, so has nothing to do with handles in server.
