Latest Patents

Kumar's latest patents focus on systems and methods for caching HTTP POST requests and responses. His innovative approach addresses the challenge of using idempotent POST requests, where the URL and headers cannot serve as an HTTP cache key. To effectively cache these requests, Kumar's method involves digesting the POST body and appending it to the URL, creating a unique cache key. This allows subsequent requests with the same payload to hit the cache instead of the origin server. The implementation includes a forward cache proxy at the client end and a reverse cache proxy at the server end. When a client sends a request to the forward proxy, it checks the cache. If there is a cache miss, the forward proxy digests the body and sends only the digest to the reverse proxy, which then looks for a match in the request cache before forwarding the request to the server.
