EmployeeJust create an arbitrary variable in the HTTP_REQUEST event and look for it in the HTTP_RESPONSE event. Example:
when HTTP_REQUEST {
set GUID [format %09d [expr {int(rand() * 1e9)}]]
send something to logs...
}
when HTTP_RESPONSE {
if { [info exists GUID] } {
send something to logs...
unset GUID
optionally unset the variable
}
}
The most important thing is that you test for the existence of the variable in the response before trying to use it.
