<para>The TCP initial congestion window or <literal>InitialCongestionWindow</literal> is used during the start

of a TCP connection. During the start of a TCP session, when a client requests for a resource, the server's initial congestion window
|

determines how many data packets will be sent during the initial burst of data. Takes a number between between 1 and 4294967295 (2^32 - 1).

Defaults to unset.

<para>The TCP receive window size or <literal>InitialAdvertisedReceiveWindow</literal> is the amount of receive data (in bytes)

an acknowledgment and window update from the receiving host. Takes a number between 1 and 4294967295 (2^32 - 1). Defaults to unset.
