First of all my sincere thanks.
Error Log Entry : [2007/12/27 10:44:07 [error] 2625#0: *7 connect()
failed (111: Connection refused) while connecting to upstream, client:
192.168.0.234, server: localhost, request:
"GET /KdocProj/dboard.html?_dc=1198726407859 HTTP/1.0", upstream: "
http://192.168.0.241:8080/KdocProj/dboard.html?_dc=1198726407859", host: "
Let me explain a few things.
The machine where I am testing the hosting is 192.168.0.241.
nginx is hosted on port 8000 and jetty on 8080 on the same machine mentioned
There is a statement in the error log like : "while connecting to upstream,
client: 192.168.0.234,", please note that 192.168.0.234 is the local proxy
server for internet access. So, what i think happening here is that nginx is
trying to access the local jetty server via proxy.
>>>>The "Connection refused" usually means that backend does not listen
on 192.168.0.241:8080 or its listen queue is full: it can not handle all
I am the only one testing this implementation. So, I dont think the listen
queue is full and also I made sure that jetty is listening on port 8080.
PS: I appreciate for your quick reply. Frankly I haven't hoped for such
quick reply. Hope you do well in the future.
