Yeah, I just noticed that. The cache functionality introduced in HAProxy 1.8, as it said, small object cache, which means that only small response can be cached, which defaults to 16KB as defined by the global parameter `tune.bufsize`. There is no such limitation in nuster, and nuster can do more things like cache based on request url/query/header/cookie, response headers, request rate, TTL, etc.
