Ok...
Assuming you have a tiles layout definition like:
<definition name=".basic.layout" path="/common/mainLayout.jsp">
<put name="header" value="/common/headerTile.jsp" />
<put name="content" value="" />
<put name="footer" value="/common/footerTile.jsp" />
</definition>
You can make the header content a tile definition by itself, and use that
definition to declare your Controller class, which will be the one with the
logic for forwarding:
<definition name=".basic.layout" path="/common/mainLayout.jsp">
<put name="header" value=".basic.layout.header" />
<put name="content" value="" />
<put name="footer" value="/common/footerTile.jsp" />
</definition>
<definition name=".basic.layout.header" page="/common/headerTile.jsp"
controllerClass="my.package.HeaderController">
</definition>
And put the forward inside the HeaderController class:
public void execute(ComponentContext tileContext, HttpServletRequest
request,
HttpServletResponse response, ServletContext servletContext) throws
Exception {
HttpSession session = request.getSession(false);
if(null == session || null == session.getAttribute("loginForm")) {
response.sendRedirect("/index.jsp");
}
}
Also, make sure that your '/common/mainLayout.jsp' page doesn't have any
html code before the <tiles:insert attribute="header" /> invocation, or it
will make a response being sent to the client.
