+ * Window size is primarily controlled by the writer. A stream can only be
+ * read by a window size equal to or greater than the one use to compress
+ * it initially. The default windows size is also the maximum window size.
+ * Thus:
+ *
+ * Outbound window size can be limited unilaterally under the assumption
+ * that the opposite end will be using the default (maximum size which can
+ * read anything)
+ *
+ * Inbound window size must be limited by asking the remote endpoint to
+ * do so and it agreeing.
+ *
+ * Context takeover is also primarily controlled by the writer. If the
+ * compressor does not clear its context between messages then the reader
+ * can't either.
+ *
+ * Outbound messages may clear context between messages unilaterally.
+ * Inbound messages must retain state unless the remote endpoint signals
+ * otherwise.
+ *
+ * Negotiation options:
+ * Client must choose from the following options:
+ * - whether or not to request an inbound window limit
+ * - whether or not to signal that it will honor an outbound window limit
+ * - whether or not to request that the server disallow context takeover
+ *
+ * Server must answer in the following ways
+ * - If client requested a window size limit, is the window size limit
+ * acceptable?
+ * - If client allows window limit requests, should we send one?
+ * - If client requested no context takeover, should we accept?
+ *
+ *
+ *
+ * All Defaults
+ * Req: permessage-compress; method=deflate
+ * Ans: permessage-compress; method=deflate
+ *
+ * # Client wants to limit the size of inbound windows from server
+ * permessage-compress; method="deflate; s2c_max_window_bits=8, deflate"
