getCache

public static Cache getCache(javax.servlet.jsp.PageContext pc,
                             int scope)

                                           javax.servlet.jsp.PageContext pc)

This function generates the key to the cache. It creates the key by suffixing the servlet path with either the user-specified key or by keeping a counter in the request attribute which it will increment each time so that multiple cache tags in a page each get a unique key.
