Jinge, please stop posting new conversations about the same issue with a different subject line.
"Http traffic not go to backend transparent" is about the same issue as "ACL HTTP not capture all the HTTP traffic ?" and "lots of connections stay in FIN_WAIT2 and CLOSE_WAIT" about the exact same thing which has already been discussed in your topic "HAproxy Server large number of connections". If you have additional questions or informations to add, just post in the old topic, but DO NOT mail the exact same problem with a different subject line. Lukas
