Ressources et spécifications sur HTTP
=====================================

HTTP a été spécifié pour la première fois au début des années 1990. Conçu dans un souci d'extensibilité, il a fait l'objet de nombreux ajouts au fil des ans, ce qui a entraîné la dispersion de sa spécification dans de nombreux documents de spécification (au milieu d'extensions expérimentales abandonnées). Cette page répertorie les ressources pertinentes sur HTTP.
