Greetings! To me it is not clear, why in tvb in function dissect_http always there is object HTTP where it is located general_header and response_header??? As well as whence I can save in a file general_header and response_header (all fields) package HTTP???? Also how it is possible to save 1 and last packages HTTP??? Thankful in advance!
