<div> when I visit it via the nginx proxy, the IE is always waiting for about the keepalive timeout, then render the image but not full, the image size is about 32K.</div><div> when I visit the image by a browser directly there is no problem, the image size is about 35K. </div>
<div> So I turn on the nginx debug, the error seems ok, at the end there is a upstream read timeout.</div><div> I did a tcpdump, the nginx box got all the response content, but the upstream(124.115.14.23) 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.</div>
<div><br></div><div> nginx is 0.7.24. kernel is 2.6.16.</div><div> so what can I do? upgrade the kernel?<br clear="all"><br>-- <br>Best Regards,<br><br>薛 勇<br><br>QQ:312200<br><br><a href="mailto:e-mail%3Aultraice@gmail.com" target="_blank">e-mail:ultraice@gmail.com</a><br>
