Hi, We're getting quite a few BADREQ entries in the logs, and we're thinking its because some clients are accumulating a lot of cookies. Is HAPROXY returning 400 Bad Request when a request or cookie or header size is exceeded? If so, is there a way to turn off these checks? We're using the latest haproxy downloaded from the 1wt website. Here's a tcpdump of one of the sessions:
