* to make filter installation decisions, you must use the pre_connection
* or install_network_transport hook. This hook should close the connection
* if it encounters a fatal error condition.
*
* @param p The pool from which to allocate the connection record
* @param server The server record to create the connection too.
* @param csd The socket that has been accepted
* @param conn_id A unique identifier for this connection. The ID only

* @param sbh A handle to scoreboard information for this connection.
* @param alloc The bucket allocator to use for all bucket/brigade creations
* @return An allocated connection record or NULL.
