This is the url,
when I visit it via the nginx proxy, the IE is always waiting for
the keepalive timeout, then render the image but not full, the image
when I visit the image by a browser directly there is no problem,
image size is about 35K.
So I turn on the nginx debug, the error seems ok, at the end there
upstream read timeout.
I did a tcpdump, the nginx box got all the response content, but
upstream(188.8.131.52) did not close the connection. After about 3
seconds,( I set keepalive timeout 3), nginx box sent a FIN packet to the
upstream, then receive a FIN.
nginx is 0.7.24. kernel is 2.6.16.
so what can I do? upgrade the kernel?
