[VB6] Scaricare pagine HTML usando comandi HTTP

**jabjoint** · 27-10-2006, 11:21

Per intanto utilizzo telnet
Prima mi connetto all' indirizzo: www.yahoo.it, porta:80
Poi scrivo:

get / HTTP/1.0 (e premo due volte invio)

In risposta ottengo questo messaggio:

HTTP/1.1 304 Not Modified
Date: Fri, 27 Oct 2006 09:13:18 GMT
Connection: close

Se mi connetto a yahoo.COM ed eseguo lo stesso comando, ottengo il codice HTML di una pagina ma non quella iniziale che mi server:

HTTP/1.1 200 OK
