In the Enable Throttling parameter, select Yes. The existing throttle configuration will appear in the wizard as shown in the example below.
Configure the following parameters as required to update the throttle policy.
| Parameter Name | Description | ||||||||
|---|---|---|---|---|---|---|---|---|---|
| Maximum Concurrent Accesses | The maximum number of requests served concurrently by the service at any given time. | ||||||||
| Range | The range of IP addresses or the domain (based on the value selected for the Type parameter) to be restricted from accessing the service. Requests from these IP addresses/domains will be restricted based on the specified values. | ||||||||
| Type | This specifies the basis on which the clients should be restricted from accessing the proxy service. Possible values are as follows.
| ||||||||
Max Request Count
| This parameter specifies the maximum number of requests that should be handled within the time interval specified in the Unit Time parameter.
| ||||||||
Unit Time (ms)
| The time interval for which the maximum number of requests specified for the Throttle ID in the Max Request Count parameter apply.
| ||||||||
Prohibit Time Period (ms)
| If the number of requests entered in the Max Request Count parameter is achieved before the time interval entered in the Unit Time (ms) parameter has elapsed, no more requests are taken by the inflow throttle handler for the time period entered in this parameter. Entering a value in this parameter alters the unit time. For example: Max Request Count = 50 If 50 requests are received within 35000 milliseconds, no requests will be taken for the next 5000 milliseconds. Thus, the time slot considered as the unit time is changed to 40000 milliseconds. If no value is entered in the Prohibit Time Period (ms) parameter, no requests will be taken until 15000 more milliseconds (i.e. the remainder of the unit time) have elapsed.
| ||||||||
| Access | This parameter is used to specify he extent to which the IP addresses/domains specified in the Range parameter are allowed access to the service to which the throttle policy is applied. Possible values are as follows.
