Question

I have a SharePoint2010 site that I have created an ASP.NET menu control for.
The ASP.NET menu’s content is initially empty, and on Page_Load I load its content from standard HTML files on the server:

           protected void Page_Init(object sender, EventArgs e)
        {
            string MenuPath = (string)ConfigurationSettings.AppSettings["RootMenuPath"].ToString();

            Menu1.Items[0].ChildItems[0].Text = File.ReadAllText(MenuPath + "\\About.htm");
//etc...
}

I notice this is a horrible way to do things. It hits the disk every single time a user loads a page.

How can I either:

a) Cache the code and asp.net menu item so that it stays in memory?

b) Use another method to ensure it isn’t loaded from the disk?

Thanks

You can wrap data load into property and use at least page Cache there:

 readonly object cacheLock = new object();
string AboutHTM
{
    get
    {
        if (Cache.Get("page.about") == null)
            lock (cacheLock)
            {
                if (Cache.Get("page.about") == null)
                    Cache.Insert(File.ReadAllText(MenuPath + "\\About.htm"));
            }
        return Cache["page.about"].ToString();
    }
}
