Concurrent HTTPS possible?

I notice that the behaviour or HTTP and HTTPS behaviours are different:

q)\s4iq)/ Single HTTPS queryq):https://example.com “GET / HTTP/1.1\r\n\r\n” / This works fine…q)/ Concurrent HTTPSq):https://example.com peach 10#enlist"GET / HTTP/1.1\r\n\r\n" / This errors 'conn. OS reports: The requested protocol has not been configured into the system, or no implementation for it exists.......q)/ Concurrent HTTPq):http://example.com peach 10#enlist"GET / HTTP/1.1\r\n\r\n" / This works fine, too`

May I know if there is any limitation in OpenSSL that caused this difference in behaviour? Or, is it possible to perform concurrent HTTPS queries in kdb+?

Thanks, I think I’ll use curl.c (https://github.com/KxSystems/kdb/tree/master/c/c) instead, after some wrapping up as a DLL: https://github.com/FlyingOE/qURL
