Dear Nic:
I got a problem. It's some sense off-topic, but the problem comes out from a
servlet
problem. Below is the problem:
In servlet A, I open a socket connection to host H, where there is a servlet
running as
a server program. And I send something to that servlet. In host H, the
servlet receive
the information sent by A and process it. After that, write something back
to A. Then
A read the information from it and close the connection.
I implemented it and sometime encountered some io problem. Someone told me,
I
should open two socket connections, one for writing to host H, the other one
for reading
from H. Is it right? Do I need to do that? Is my way of communication
correct?
Thanks for your consideration!
Regards
Liwen
