I recently migrated my web server to Litespeed. However, clients are complaining that they couldn't open my web pages. I did all kinds of tests and here is a summary: My web server does not respond to the first http request by any PC. However, after the first http request, everything is fine. It's just the first http request to my web page has problem, after the PC reboots and get a new IP. I used ethereal sniffer and captured that LiteSpeed server sended back a RST packet right after a ACK packet after connection established. Most PCs during the test are directly connected to the Internet without any firewall/proxy servers. The web server is on the internet without any firewall before the PCs reach it. My server is running: Lite Speed 2.2.2 standard. [root@test ~]# uname -a Linux test 2.6.17-1.2187_FC5 #1 Mon Sep 11 01:17:06 EDT 2006 i686 i686 i386 GNU/Linux I've set up a test server on the Internet, so you can test it here: http://220.127.116.11 and http://18.104.22.168/test.html Could this be a bug? Thanks.
