This one might be a little faster:

  r1 = Regexp.new(/\.(?:css|jpg|gif|CSS|JPG|GIF) HTTP/)
  r2 = Regexp.new(/^192\.(9|18|29)\./)
  File.open(ARGV[1], 'w') { |out|
    File.open(ARGV[0]).each_line { |line|
      next if r1.match(line) or r2.match(line)
      out.print(line)
    }
  }

using strscan may give it another boost and
running under ruby 1.7 may be faster still.

I don't have java installed to compare the original...
