Networking - ssl socket closure server side
Hi All,
Just a quick query regarding socket(blocking) closure using ssl on the server side.
Thread 3 is writing to an SSL socket and got into a situation where the client has stop reading. hence once the tcp/ip write buffer fills up, Thread 3 blocks on the write.
I`m trying to close this socket hence, I have another thread (Thread 1) that is trying to close this socket if Thread 3 is blocked for too long. The stack trace below indicates that Thread 1 is trying to send a message to the client but since the write buffer is already full, thread 1 ends up getting blocked as well.( trying to send an ssl alert message)
Trying to do the same thing on the client side can be done using SSL overlay
(create a normal socket, overlay an SSL socket on top of this) close the normal socket does not block. (I`m not sure what the implication of this means in terms of the SSL protocol).
Any Ideas how this can be done on the server side?
Thank you
