PagePool/ProxyTrace loads the requeststream during initialization phase, so it does not need a randomvariable for request interval; see its description below. <P>An example of using PagePool/Math is at Section<A HREF="node520.html#sec:webcache-example" tppabs="http://www.isi.edu/nsnam/ns/doc/node520.html#sec:webcache-example">36.8</A>.
