High Speed Logging event correlation

With the logging profile, I don't know that there is a way to assign a unique ID to each request/response entry, but you could accomplish this with an iRule that handles your HSL. You would just need to set a variable in the HTTP_REQUEST even and log it, then use that variable in the HTTP_RESPONSE event to write your log. You could try setting an ID with somethign liek this,

set ID [md5 "[clock seconds][IP::client_addr][TCP::client_port]"]
