Most protocols are documented in RFC's, such as these: http://www.w3.org/Protocols/rfc2616/rfc2616.html http://ftp.ics.uci.edu/pub/ietf/http/rfc1945.html http://www.ietf.org/rfc/rfc0959.txt http://www.faqs.org/rfcs/rfc768.html http://www.ibiblio.org/pub/docs/rfc/rfc793.txt >Lastly, where should I go to read up on how to make my scripts run >faster?

Knuth's quote, "We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil", was probably intended to refer to optimizations like those. I wouldn't worry about them, especially if shaving a few milliseconds off your script is going to make it a nightmare to debug or revisit. --------------------------------------------------------------------- michal migurski- contact info and pgp key: sf/ca http://mike.teczno.com/contact.html
