I have discovered that this problem is related to a work around
implemented in openssl 0.9.6d and the work around can be switched on/off
in openssl-0.9.6e and above. To do this, I need to be able to
SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS option in the ssl context of the
socket created my HTTPSConnection.
I don't see a way of doing this using the current API? I think I
essentially need access to the openssl methods SSL_set_options() or
maybe SSL_CTX_set_options(). Does anyone know how I can set this context
option from python?
