# Optional: Configuring ASE persistent connections

You can optionally configure TCP keep-alive connections in the `ase.conf` file of API Security Enforcer (ASE).

## About this task

To configure TCP keep-alive connections:

## Steps

* Set the `enable_sideband_keepalive` variable to `true`.

  The following snippet is from `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
  ```
