Parameters may include quoted strings as values, and quoted strings may include separators such as ';', ',', and '/', as well as backslash-escaped characters including escaped quotes "\"".

  Personally, I can see the appeal in deliberately failing to parse those requests properly, just to discourage it. I'm for standards as much as the next guy, but if the difference between 99% and 100% compliance is five hours work and a parsing routine that's an order of magnitude more complex, well...

  
  It's like those people who produce hideous but technically well-formed RFC2822 addresses and expect the rest of us to deal with them. It's the sort of idiocy that leads to the "short" email-matching regular expression in Friedl's book needing 4724 characters, and even then it doesn't cover every case.

  Use the csv module to do the splitting - it takes care of quoting.
