(2008.05.22, 06:33) Hi, all.
We are experiencing a bizarre problem involving LVS, SSL and Internet Explorer. We are looking for insights and, possibly, a solution. We have an LVS cluster comprised of one load balancer connecting to six real servers. Each real server serves Apache requests to a ,cgi script located on a backend server that is accessed by each node using NFS. This setup has worked well so far, both using regular requests and SSL requests. A problem appeared last week soon after we migrated the cluster from using public IP addresses for real servers to using local (192.168) IP addresses (i.e., we went from DR to NAT). Non-SSL requests are handled fine. SSL requests made directly to the backend server (i.e., avoiding the LVS cluster) are handled fine. SSL request handled by the LVS cluster are fine if they are issued by any browser other than Internet Explorer 5 (and Internet Explorer 6 in the case of one tester). But Internet Explorer 5 SSL requests to the load balancer are sometimes handled correctly, but, other times, they either return the same page instead of the requested page or they return a browser error page (browser cannot reach the page). To add to the difficulty, it appears that these errors are not actually produced by the Apache server: one of the testers has a slow Internet connection and can clearly feel a lag when the next page is being properly processed; when an error page is returned, it comes up immediately, suggesting that no Internet communication took place. Can anyone suggests where we should pursue our investigation? Thanks in advance.
