httpd and detecting tcp_close
Mon Jul 20 21:17:28 CEST 2009
I'm pretty sure you could hack it to do so, but I don't use httpd.
I can tell you how I handled the situation last year when I wrote a
Java/Jetty based long poll server that had the same problem. There was
no way to hack Jetty to detect the close, so I had to add a timeout
for every client on the server. Basically the long poll returned every
30 seconds, and the client would immediately re issue the poll.
If the server did not get a long poll from the client within 60
seconds it would presume it was closed. This worked although sub
optimal because it could take up to 60 seconds to detect a lost
client. However it was the only option I could find.
