It was Richard Newman who said at the right time 17.04.2009 23:57 the following words: >>> Are Long URLs wasting bandwith? >>> http://tech.slashdot.org/article.pl?sid=09/03/27/2017250&from=rss >> >> It's been a few years since I went as far down the protocol stack as >> TCP/IP, but don't TCP packets have a minimum size? I would have >> thought that most HTTP requests would fit into a single packet, with >> no difference to the packet size. Or is my memory faulty here? > > It depends on the underlying transport protocol. If your IP traffic is > going over an ATM switch, your data is being broken down into 48-byte > frames, in which case saving a few bytes in URL length can make a > difference of a frame or two for every request. > > On the other hand, if every host en route is using Ethernet-size > packets, on the order of 1500 bytes, then yes, HTTP requests will > typically fit into a single packet. finally a technical thread on this list! I had to wait for years to see this happen. 8-] greetings to Juan, thanks to Richard for the analysis, Leo -- ____________________________________________________ DI Leo Sauermann http://www.dfki.de/~sauermann Deutsches Forschungszentrum fuer Kuenstliche Intelligenz DFKI GmbH Trippstadter Strasse 122 P.O.
