You can also specify the throttle policy within a proxy service configuration as a key by saving the policy in the registry or by saving it as a local entry. However, when you are not using the Management Console, you are required to manually create an entry in the <ESB_HOME/repository/deployment/server/servicemetafiles/<Service_Name>.xml file to enable throttling as shown in the example below. | Code Block |

The proxy service configuration in this example can be as follows. | Code Block |
|---|
| <?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
name="ThrottleProxy"
transports="https http"
startOnLoad="true"
trace="disable">
<description/>
<target>
<endpoint>
<address uri="http://localhost:9000/services/SimpleStockQuoteService"/>
</endpoint>
<inSequence>
<log level="full"/>
</inSequence>
</target>
<policy key="throttlePolicy1"/>
</proxy> |
The following is an example of a throttle policy configuration that can be saved in the registry or as a local entry. | Note |
|---|
You need to use the same string (e.g., throttlePolicy1) fot for the throttle policy key of both the proxy service configuration, and the local entry definition, which is saved in the registry. |
