Time. Messages are sorted in chronological order of time sent or received.
URL. Messages are sorted by URL address. Multiple messages with the same address are sorted by time.
Connection. Messages are sorted by communication connection. Messages using the same connection are sorted by time. This sort type enables you to see messages grouped by requests and their associated responses.
Note - Sorting parameters are dependent on the message protocol you choose. For instance, sorting by time is not relevant for socket messages.
