So, how do you deal with multi-fork files, byte ranges from generated output streams, ranges that are interpreted as records in a database or any other number of problems? It certainly complicates the caching of this stuff. Also, how can a proxy be expected to reconstruct a document from a sparse set of byte range requests (e.g, 1-100, followed by 45000-45100, followed by 3000-3300, followed by 99-45001)? I understand your motivation here, but proxy implementation is going to be a nightmare if you really try to build it this way. >The spec is written so as to make this work through existing proxies >without support for it, to intentionally break with servers that don't >have support for it, and to make it work in clients without adding >more interaction and complexity between HTML and HTTP. What do you mean by "intentionally break" with servers that don't support it? ----------------------------------------------------------------------- Chuck Shotton cshotton@biap.com http://www.biap.com/ cshotton@oac.hsc.uth.tmc.edu "I am NOT here."
