Question

I’m trying to preload the output cache in mvc4 application using WebActivator. I figured I could simply make an async call to a few routes and that would do the trick. Unfortunately, I can’t find the Root Url to my app anywhere… There is no current httpRequest.

Here is what I’d like to do.

[assembly: WebActivator.PostApplicationStartMethod(typeof(MaidBrigade.Web.App_Start.CacheLoader), "Load")]
namespace MaidBrigade.Web.App_Start
{
  public class CacheLoader
  {
    public static void Load()
    {
      var client = new HttpClient();
      var root = ""; // Where can a fetch this from?      
      client.GetAsync(root + "/vision/marketing/NationalReportData");

    }
  }
}

Try using:

var root = Url.Content("~/");

or:

var root = Url.Content("~");

Also try:

string.Format("{0}://{1}{2}", Request.Url.Scheme, Request.Url.Authority, urlHelper.Content("~"));

And if Request is not available, try:

var request = HttpContext.Current.Request
