I'm building an application that will shutdown a server, ping that server, and notify the user if the server has been shutdown. If it does not shutdown successfully, it allows the user to "Try Again". I can get the application to process the logic correctly the first time but when I implement the "Try Again" feature, it does not reprocess the Shutdown action. I think it must have something to do with caching but I don't know enough about it to know where to start looking. Any ideas?
Here is my code:
Controller
//URL: Build/Progress
public ActionResult Progress()
{
return View();
}
////URL: Build/MoveDevice
public ActionResult ShutdownStatus()
{
ImageInfo ImageInfo = new ImageInfo();
FarmInfo FarmInfo = new FarmInfo();
ProgressModel ProgressModel = new ProgressModel();
if ((Session["ShutdownStatus"] as string) == "Success")
{
ProgressModel.ShutdownStatus = 1;
return View(ProgressModel);
}
else
{
ImageInfo = svcImage.GetImageInfoByImageId(Session["ImageName"].ToString());
string Farm = ImageInfo.FarmId.ToString();
FarmInfo = svcFarm.GetFarmByFarmId(Farm);
svcImageSvc.ShutdownDevice(Session["Username"].ToString(), Session["Password"].ToString(), Session["Domain"].ToString(),
FarmInfo.farmName, ImageInfo.Device, ImageInfo.ImageHistory.Status, ImageInfo.PVSHost, ImageInfo.PVSAccount);
ProgressModel.ShutdownStatus = svcImageSvc.PingDevice(ImageInfo.Device);
return View(ProgressModel);
}
}

I believe the caching is actually being done by jQuery. Change the $.get to a $.post and see if it works. If it does, you can still use $.get, but you will need to set the option:
cache: false
