HTTP/1 has suffered from CRLF injection attacks, content-length bounds check failures, a wide variety of line ending interop problems, etc.. all of which are derived from its text roots. Sometimes these problems are unforseen spec issues, but sometimes they are just derived from assumptions people have because the text format feels more intuitive than it really is. While text is convenient to eyeball, it is much harder to get unambiguously correct especially in a open multiple implementation environment. 32 bits of big endian is well defined and well bounded; a text string that represents a quantity requires a lot more information to correctly interpret. http://blog.jgc.org/2012/12/speeding-up-http-with-minimal-protocol.html#c5703739431744738432 Frankly, I'd rather talk about byte order.. imo this is an application level protocol that 98% of the time is going to be consumed by little endian processors and could easily be defined that way. This of course runs against tradition and isn't a huge deal computationally, but I'm not aware of other arguments against giving the byte swap operation of our processors a day off.Received on Monday, 21 January 2013 15:04:38 GMT
