I was not able to connect to any website using a http proxy. The problem is not with your web client, it's with your connection to the proxy. Your proxy doesn't want to talk to your machine. I am assuming that the proxy does accept a connection when you are running kernel 2.2.x, but rejects it under 2.4.x, correct? If this is not so (the proxy refuses you regardless of kernel version) then you need to ask the proxy administrator; it's their problem, not linux's. But assuming the refused connections occur with 2.4.x, then what is most likely happening is that you have compiled CONFIG_INET_ECN into your kernel. As the documentation says, many firewalls (at notable sites) refuse connections from machines with ECN enabled. See if the file /proc/sys/net/ipv4/tcp_ecn exists when you are running 2.4.x. If so, do 'echo 0 > /proc/sys/net/ipv4/tcp_ecn' and try your proxy again.
