How to clear the client-side .Net SSL session cache

I am writing a little test tool, which uses HttpWebRequest to load test a server. I want for each time I try to call HttpWebRequest.GetResponse() for it establish a fresh SSL session instead of using the one in the cache. Note: I am supplying a client certificate, and using Mutual Authentication for the SSL Session.

Is there a way to clear the SSL Session cache referred to in http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.clientcertificates.aspx ?
