Patent number: 8959237Abstract: A method of web services throttling in a web application server environment, where a number of web services servers communicate with web services clients over a network. A request is received from a web services client which contains an account ID related to the web services client. An ID reader resident on one of the web services servers reads the account ID; and a value related to the account ID in a counter, resident on the one of the services servers, is incremented. The method also involves communicating with the remaining web services servers to increment the value in a plurality of counters, each of which is resident on one of the remaining web services servers. The web services servers compare the count value related to the account ID to a throttling limit value.Type: GrantFiled: September 3, 2010Date of Patent: February 17, 2015Assignee: Cellco PartnershipInventors: Zhijian Lin, Wei Guang Tan, Lodema Steinbach
