Programmazione:MIME types

Elenco

I MIME type primari sono due:

• text/plain è il valore di default per i files di testo. Questi files sono umanamente leggibili e non devono contenere dati binari.
• application/octet-stream è il tipo di default per tutti gli altri tipi che non siano i files di tipo testo.

L'IANA è il registro dei media type e ne mantiene una lista ufficiale lista
