El servidor web emmagaztema el registre (log) dels accessos a l'arxiu 'access.log'. Cada accés s'emmagatzema en una línia de l'arxiu amb aquest format:

%h %l %u %t "%r" %s %b "%f" "%a"

El significat d'aquests camps és el següent:

  • %h és l'adreça IP del client que ha realitzat la petició al servidor
  • %l és la identitat de la màquina del client
  • %u és l'userid de la persona determinada per l'autenticació HTTP
  • %t és el temps en que s'ha rebut la petició. El format és:
[day/month/year:hour:minute:second zone]
day = 2*digit
month = 3*letter
year = 4*digit
hour = 2*digit
minute = 2*digit
second = 2*digit
zone = (`+' | `-') 4*digit
  • %r és la lína de petició realitzada pel client. El format és:
%M %U%q %H
  • %M és el Mètode (GET, POST, ...)
  • %U és el path del recurs sol·licitat
  • %q és la query realitzada sobre el recurs
  • %H és el protocol (HTTP/1.0, HTTP/1.1, ...)
  • %s és l'status code que el servidor retorna al client
  • %b és el tamany de l'objecte retornat al client
  • %f és el lloc del qual el client reporta que ha estat referenciat
  • %a és l'user-agent: la identificació del navegador web del client

Es desitja fer una anàlisi d'aquest registre per tal d'esbrinar:

  • El host que més peticions realitza al servidor
  • El recurs més solicitat
  • El lloc que més ens referencia
  • El navegador més usat pels clients
  • L'hora del dia en que més peticions rep el servidor

Input Format

L'entrada consta de diverses línies de registre amb el format indicat. El registre acaba amb la línia __END__

Constraints

-

Output Format

S'imprimirà en distintes línies:

  • El host que més peticions ha realitzat
  • El recurs que més peticions ha rebut
  • El referrer que més ens ha direccionat
  • L'User Agent més utilitzat pels visitants
  • L'hora del dia que més peticions s'han realitzat
