When exactly does a socket timeout get triggered?
When exactly does a socket timeout get triggered?
Is it when the SO_TIMEOUT time has been reached and the first byte of data
has not been received?
Or is it when the SO_TIMEOUT time has been reached and the last byte of
data has not been received?
In other words, if you start receiving data before the SO_TIMEOUT time has
been reached, but are still receiveing data after the SO_TIMEOUT time has
been reached, does this cause a timeout or not?
Thanks,
Nate Gardner

Hi Roland,
Could u tell me how to extract the time of arrival of the first byte.

Yes. Socket timeouts are per read operation. If you receive a
response, even with only a single byte of data, before the
timeout hits, then the read operation succeeds. If you want
to read more data, you have to call another read operation,
which will start a new timeout interval. This is not specific
to HTTP, it's general socket behavior:
http://java.sun.com/j2se/1.4.2/docs/api/java/net/Socket.html#setSoTimeout(int)
hope that helps,

Yes. Socket timeouts are per read operation. If you receive a
response, even with only a single byte of data, before the
timeout hits, then the read operation succeeds. If you want
to read more data, you have to call another read operation,
which will start a new timeout interval. This is not specific
to HTTP, it's general socket behavior:
