The following is a snippet of ase.conf displaying the default enable_sideband_keepalive variable. The default value is set to false.

; enable connection keepalive for requests from gateway to ase.
; This setting is applicable only in sideband mode.
; Once enabled ase will add 'Connection: keep-alive' header in response
; Once disabled ase will add 'Connection: close' header in response
enable_sideband_keepalive=false

If this variable is set to true, then you must configure persistent connections in Axway Policy Studio:

  1. In Axway Policy Studio, go to Environment Configuration > Listeners > API Gateway.
  2. Click your ASE IP address in Sample Services.
  3. In the Remote Host Settings pop-up window, clear the Allow HTTP 1.1check box.
  4. Click the Include Content Length in request check box. Make sure all other check boxes are cleared.
  5. Click OK and deploy the policy.
