what is the best way to capture page views by person without slowing down performance on the site. I see that stackoverflow show page views all over the place. Are they doing an insert into a db everytime i click on a page?
In asp.net-mvc, Is there any recommended way to track page view per user (my site has a login screen) so i can review which pages people are going to and how often
First off.. if what you really care about is how are customers using my site then you most likely want to look into Google Analytics or a similar service.
But if you want a quick and dirty page view record and you are using ASP.Net MVC 3 then as Chris Fulstow mentioned you're going to want to use a mix of global action filters and caching. Here is an example.
PageViewAttribute.cs
public class PageViewAttribute : ActionFilterAttribute
{
private static readonly TimeSpan pageViewDumpToDatabaseTimeSpan = new TimeSpan(0, 0, 10);
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
var calledMethod = string.Format("{0} -> {1}",
filterContext.ActionDescriptor.ControllerDescriptor.ControllerName,
filterContext.ActionDescriptor.ActionName);
var cacheKey = string.Format("PV-{0}", calledMethod);
var cachedResult = HttpRuntime.Cache[cacheKey];
if(cachedResult == null)
{
HttpRuntime.Cache.Insert(cacheKey, new PageViewValue(), null, DateTime.Now.Add(pageViewDumpToDatabaseTimeSpan) , Cache.NoSlidingExpiration, CacheItemPriority.Default,
onRemove);
}
else
{
var currentValue = (PageViewValue) cachedResult;
currentValue.Value++;
}
}
private static void onRemove(string key, object value, CacheItemRemovedReason reason)
{
if (!key.StartsWith("PV-"))
{
return;
}
// write out the value to the database
}
// Used to get around weird cache behavior with value types
public class PageViewValue
{
public PageViewValue()
{
Value = 1;
}
public int Value { get; set; }
}
}
And in your Global.asax.cs
public class MvcApplication : HttpApplication
{
public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
filters.Add(new PageViewAttribute());
}
}
For pre-ASP.Net MVC 3 ONLY you are going to have to apply the same attribute manually to all of your actions.
[PageView]
public ActionResult CallOne()
{
}
[PageView]
public ActionResult CallTwo()
{
}
