It is much less complicated than you are imagining. <%@ include %> is a
static compilation, means that effectively /jsp/loginpanel.jsp and
/log/logoutpanel.jsp are cut and paste into your main JSP before it is
compiled. There is no caching or recompiling or anything, anymore than
the following code would be recompiled or cached specially:
<%
if (user == null) {
%>Red<%
} else {
%>Blue<%
}
%>
