Web service multi-key rate limiting method and system
First Claim
1. A method for limiting a number of web service programming calls, the method comprising:
- intercepting a web request for web service programming from a client;
extracting call specific data from the web request, wherein the web request includes at least one of;
a client identifier, an application identifier and a client IP address;
generating a plurality of hashes from the call specific data;
accessing a transport module to determine which of the plurality of rate limiter servers to send the hashes;
transmitting the hashes to a plurality of rate limiter servers;
on the rate limiter servers, calculating a total number of web requests, identified by the hashes;
receiving web request totals from the rate limiter servers; and
determining accessibility of the client to the web request based on a comparison of the number of web requests for the web service programming relative to a predetermined access limit.

Abstract
The present invention provides a method and computer system for limiting a number of web service programming calls including intercepting a web request for web service programming from a client and extracting call specific data from the web request. The method and computing system further includes transmitting call specific data to a plurality of rate limiter servers and on the rate limiter servers, calculating a total number of web requests, where the web requests are identified by the call specific data. The method and computing system further includes receiving web request totals from the rate limiter servers and thereby determining accessibility of the client to the web request based on a comparison of the number of web requests for the web service programming relative to a predetermined access limit.
