 *  Fix: Don't crash decompressing web sockets messages. We had a bug where we assumed deflated
    bytes in would always yield deflated bytes out and this isn't always the case!

 *  Fix: Reliably update and invalidate the disk cache on windows. As originally designed our

	// certain bytes in the input stream occur more frequently than others.
	//
	// Note that HuffmanOnly produces a compressed output that is
	// RFC 1951 compliant. That is, any valid DEFLATE decompressor will
	// continue to be able to decompress this output.
