form, post e http

[willypuzzle]

Ciao a tutti io ho il seguente form(che poi è il form della pagina di google per l'autenticazione). Vorrei sapere, a livello di protocollo http, quali sono i vari header che vengono generati e vengono passati con il metodo post al server quando l'utente clicca su "Accedi".
Grazie tante e a presto.
