Re:Re: [Libevent-users] https-client sample problem on libevent 2.1.7

Hi,

I've tried the advice about the output headers (host & connection:close), after that I can make several request on the same connection, but the problem is still the same once the server side response with "Connection:Close".

I also captured the network packets between client(172.19.10.40) and my HTTPS web server(10.206.0.46) with wireshark, please find "https.pcap" in the attachment, the last few packets of which shows the client who send the FIN just after successfully reconnected to the server, even not yet did any HTTPS handshake.

So I think probably it is the problem of client.

I'm trying to dug deep into the bufferevent_ssl layer to track the problem, any body can help?
