Do you mean browser session or TCP connection? If the latter then very easy as all variables are scoped for TCP session;-

when STREAM_MATCHED {
   if {![info exists fBananaSeen]} {
       Set variable
      set BananaSeen 1
      log local0. "Banana seen for this TCP connection"
   }
   STREAM::disable
}

No need to delete anything when connection closes as variable automatically cleared.
