I create a simple module which has a button. When user clicks it, it generates an event linking to other .ascx file in the same module. It can be in the same page or different page.

Dim objModules As ExModuleController = New ExModuleController
Response.Redirect(NavigateURL(58, "MyEx", "mid=392&giatri=1"))

If I log in as a host, everything is fine. However, if I log out and run as a guest, it doesn't work as I want. Sometime it runs but almost does nothing. How can I fix it? Please help me.

I put this module in 2 differrent page. The first page is the child of Home page. The second page has no parent. The module in the second page runs fine while module in the first page can not run.

I have debugged and found that it doesn't fire the buttons' click events in module in the first page. I don't know why. Here is the code:

 protected void Button1_Click(object sender, EventArgs e)
        {

            DotNetNuke.Entities.Modules.ModuleController objModules = new DotNetNuke.Entities.Modules.ModuleController();
            Response.Redirect(DotNetNuke.Common.Globals.NavigateURL(59));

        }

        protected void Button2_Click(object sender, EventArgs e)
        {

            DotNetNuke.Entities.Modules.ModuleController objModules = new DotNetNuke.Entities.Modules.ModuleController();
            Response.Redirect(DotNetNuke.Common.Globals.NavigateURL(PortalSettings.ActiveTab.TabID, "controlCS", "mid="+ModuleId));
        }

        protected void Button3_Click(object sender, EventArgs e)
        {

            DotNetNuke.Entities.Modules.ModuleController objModules = new DotNetNuke.Entities.Modules.ModuleController();
            Response.Redirect(DotNetNuke.Common.Globals.NavigateURL(59, "controlCS", "mid=394" ));
        }

        protected void Button4_Click(object sender, EventArgs e)
        {

            DotNetNuke.Entities.Modules.ModuleController objModules = new DotNetNuke.Entities.Modules.ModuleController();
            Response.Redirect(DotNetNuke.Common.Globals.NavigateURL(59,"", "giatri=2"));

        }

        protected void Button5_Click(object sender, EventArgs e)
        {
            DotNetNuke.Entities.Modules.ModuleController objModules = new DotNetNuke.Entities.Modules.ModuleController();
            Response.Redirect(DotNetNuke.Common.Globals.NavigateURL(59, "controlCS", "mid=394&giatri=2"));

        }

The cache time setting for a module can only be set to 0 if there is static content for the module.  If you have events that are triggered you cannot use it.  I believe of the core modules the text/html module is the only one that actually uses the cache setting.
