Answer 1

You can use windows scheduled task to run the application (exe) or create windows service and use timer. Take a look at Quartz.NET it also can used.

Answer 2

At startup, add an item to the HttpRuntime.Cache with a fixed expiration. When cache item expires, do your work, such as WebRequest or what have you. Re-add the item to the cache with a fixed expiration.

private static CacheItemRemovedCallback OnCacheRemove = null;

protected void Application_Start(object sender, EventArgs e)
{
    AddTask("DoStuff", 60);
}

private void AddTask(string name, int seconds)
{
    OnCacheRemove = new CacheItemRemovedCallback(CacheItemRemoved);
    HttpRuntime.Cache.Insert(name, seconds, null,
        DateTime.Now.AddSeconds(seconds), Cache.NoSlidingExpiration,
        CacheItemPriority.NotRemovable, OnCacheRemove);
}

public void CacheItemRemoved(string k, object v, CacheItemRemovedReason r)
{
    // do stuff here if it matches our taskname, like WebRequest
    // re-add our task so it recurs
    AddTask(k, Convert.ToInt32(v));
}
