Abstract
A method, non-transitory computer readable medium and device that assists with preventing distributed denial of service attack includes receiving a request for a web resource from a client computing device. The received requested for the web resource is determined for presence of referrer header information. When the received request is determined to include the referrer header information, then the referrer header information is checked whether it includes a known domain and a valid cookie associated with the known domain. A distributed denial of service attack is prevented by providing a proactive challenge to the requesting client computing device when received request for the web resource does not include the referrer header information or when the referrer header information comprises the known domain and does not include the valid cookie.
