Hi Volker and Renzo, the page I'm using to test memory usage is very simple and doesn't use any custom javascript or PPR.
Here is the code: /** LAYOUT **/ <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";> <tr:document xmlns:ui="http://java.sun.com/jsf/facelets"; xmlns:f="http://java.sun.com/jsf/core"; xmlns:h="http://java.sun.com/jsf/html"; xmlns:tr="http://myfaces.apache.org/trinidad"; xmlns:trh="http://myfaces.apache.org/trinidad/html"; title="Base test"> <f:view> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>RedMane Trinidad Test</title> <ui:insert name="beforeLoadScripts" /> </head> <tr:form defaultCommand="#{defaultFormCommand != null ? defaultFormCommand : 'none'}" id="mainForm"> <div id="header"><!-- HEADER MENU --> <ui:insert name="headerMenu"> <ui:include src="headerMenu.xhtml" /> </ui:insert></div> <div id="content"> <div id="menuContent"> <div id="logo"> <h1><a href="#">Your Logo</a></h1> <h2><a href="http://www.redmane.com/";>your link</a></h2> </div> <!-- LEFT SIDE MENU --> <ui:insert name="menu"> <ui:include src="menu.xhtml" /> </ui:insert></div> <div id="bodyContent"> <div id="welcome"><!-- PAGE TITLE --> <h2><ui:insert name="title">Default Page title</ui:insert></h2> <!-- ERROR MESSAGES --> <tr:messages /> <!-- PAGE CONTENT --> <ui:insert name="content"> <ui:include src="content.xhtml" /> </ui:insert></div> </div> </div> <div style="height:20px;"/> <!-- FOOTER --> <ui:insert name="footer"> <ui:include src="footer.xhtml" /> </ui:insert> </tr:form> </f:view> <ui:insert name="afterLoadScripts"/> </tr:document> /** THE PAGE **/ <tr:subform xmlns:ui=http://java.sun.com/jsf/facelets xmlns:f="http://java.sun.com/jsf/core"; xmlns:tr="http://myfaces.apache.org/trinidad";> <ui:composition template="/layout/layout.xhtml"> <ui:define name="title">Home Page</ui:define> <ui:define name="content"> Welcome <p> <tr:group rendered="#{securityContext.ifAllGranted['ROLE_TEST']}"> Testing ACEGI JSF </tr:group> </p> </ui:define> </ui:composition> </tr:subform> /** END OF CODE **/ By simply refreshing this page, the IE keeps allocating more memory. Since Firefox is behaving fine, I suppose it's an IE7 problem, so we cannot do anything about it. I also made the same tests on maps.google.com (that for what I know uses a lot of AJAX and Javascript) and it presents the same behavior! I'll maybe post something on an IE forum, but I don't expect a quick solution to the problem (or any solution at all...) from Bill...
