How to limit the current through the client_id (custom) of the request header

[ouyangli]

In my business, I need to limit the flow through the client-id in the request header, which stipulates that each client-id can only send 2 requests within 15 seconds

The configuration is as follows：

called by postman:

Expected effect: Each client-id can only send 2 requests per 15 seconds

Actual effect: all client-id can only send 2 requests every 15 seconds

The following should be considered when setting the hash_on value:

When set to vars, a key is required. The value of the key can be any of the Nginx variables without the $ prefix.
When set to header, a key is required. This is equal to "http_key".
When set to cookie, a key is required. This key is equal to "cookie_key". The cookie name is case-sensitive.
When set to consumer, the key is optional and the key is set to the consumer_name captured from the authentication Plugin.
When set to vars_combinations, the key is required. The value of the key can be a combination of any of the Nginx variables like $request_uri$remote_addr.
When no value is set for either hash_on or key, the key defaults to remote_add
