Is there a way to customize tcp buffering parameters in AX?

    Hi Jeff,

    AX can act as a Proxy or not depending on the VIP type.
    Non-Proxy VIP types: TCP, UDP.
    Proxy VIP types: all others (HTTP, FTP, HTTPS, SSL-Proxy, etc)
    Note: From release 2.6, we introduced a new type "TCP-Proxy" which is a generic TCP proxy VIP type.

    When the AX acts as a Proxy for a TCP application, then you have technically 2 distinct sessions:
    . One TCP session between Client and AX
    . One other TCP session between AX and the Server

    And AX to reply to your question, the AX will buffer the server response fast if the client is on a slow link.
    How much data the AX will buffer?
    By default the AX will buffer up to 87380 bytes per session.
    But this is configurable up to 2147483647 bytes.
    . WebUI: "Config >> Service >> Template >> TCP Proxy"
    . CLI: "slb template tcp-proxy"
    and assign that template to your VIP-port.
