Hi everybody , i have one question about HTTP/1.1 persistante connections .. if i have connection to server, the connection is in state open , the server sends me the FIN packet what should i do then ? I mean sending back FIN/ACK is the work of java librarys not ?

[BigDaddy]

Keith Maclaine, it depends...
do you close the connection?
do you work with sockets or URLConnection?

[Keith Maclaine]

BigDaddy , well i dont close connection after sending some request becouse of this should be persistante conn.

[BigDaddy]

hard to keep it persistent if the server closes...
but still, are you using sockets or URLConnection

[Keith Maclaine]

yes , sockets

[BigDaddy]

writing correct http/1.1 socket code is quite hard...
why not use an existing library?
URLConnection uses persistent connections if it can. My proxy does it as well, commons net from apache probably does to

[Keith Maclaine]

well my question is what is has to be done when my app receives for any reason FIN packet from server

[BigDaddy]

you will get a read() that returns -1 (EOF)

[Keith Maclaine]

BigDaddy, so the solution is to call a read() all the time ?

[BigDaddy]

no...
are you using blocking io or selector based non-blocking io?
