Perl secure web services using Rate limiting

 Rate limiting is a technique used to prevent clients from making too many requests to a web service in a short period of time, which can cause denial-of-service (DoS) attacks or overload the service. Here's how you can implement rate limiting to secure Perl web services:

1.Define the rate limits for each client or API key based on the number of requests allowed within a certain time period. For example, you may allow a maximum of 10 requests per minute for each client.

2.Track the number of requests made by each client or API key within the specified time period. You can use a database or in-memory storage to keep track of the request count.
