Description: Request filtering is the process of allowing or blocking requests based on certain criteria. This mechanism is fundamental in managing traffic in networks and applications, as it helps protect systems from unauthorized access and optimize performance. In the context of API gateways, request filtering allows developers to define specific rules that determine which requests can be processed and which should be rejected. These rules can be based on various parameters, such as the requester’s IP address, the content type of the request, the HTTP methods used (GET, POST, etc.), and other relevant headers. By implementing effective filtering, organizations can enhance the security of their applications, prevent attacks such as DDoS (Distributed Denial of Service), and ensure that only authorized users have access to certain resources. Additionally, request filtering can help manage server load by allowing only valid and necessary requests to be processed, resulting in a more efficient use of system resources.
