This transformation takes place transform_buffer_event() handler
function, when the data from the upstream is completely copied into
the input buffer is by the continuation TSCont from write VIO.
In the transform_connect() function, there is a communication with the
remote server (socket call) as below.
200 /* TODO: This only supports IPv4, probably should be changed at
some point, but
201 it's an example ... */
202 memset(&ip_addr, 0, sizeof(ip_addr));
203 ip_addr.sin_family = AF_INET;
204 ip_addr.sin_addr.s_addr = server_ip; /* Should be in network byte
order */
205 ip_addr.sin_port = server_port;
206 action = TSNetConnect(contp, (struct sockaddr const*)&ip_addr);
207
I am not able to understand as this does not seems to be actually sending
data to the server over this socket. So when the response from socket
(server) is indeed received, where that data will be handled to send to the
proxy client?
Thanks,
