In LoadMaster firmware version 7.2.51, a new option was introduced that is applicable when performing Kerberos Constrained Delegation (KCD) back-end authentication. The field is called L7 Wait after POST. This option is configurable in the LoadMaster User Interface (UI). The L7 Wait after POST option allows you to change the length of time to wait for a 401 response from a POST before sending the remainder of the POST body. Valid values for the wait period range from 1 to 2000 milliseconds (ms). The default value is 2000. If KCD is not being used, this option has no effect.

To configure the L7 Wait after POST value, follow the steps below:

  1. In the main menu, go to System Configuration > Miscellaneous Options > L7 Configuration.

  2. Enter the new value in the L7 Wait after POST text box and click Set Post Wait.
