ASP.Net MVC - TempData session problem

The WebFarm we are us开发者_Go百科ing doesn't supports Session. We are in a requirement to pass Data during redirects. How to do this without TempData dictionary since TempData uses Session inside.

You can write your own TempData provider and store it in cookies. See ASP.NET MVC Store TempData in Cookie Or you could have a base-class Controller that looks for a hidden input and hydrates objects / state and persists it to / from it each http request.

Note that TempData only persists between two controller actions.

Edit:

You could use the same example and write a provider that serializes to a DB ... or ... even to disk. Shoot, for that matter, you could even roll an entire custom replacement for Session. You'd create a session factory class and store your custom session objects via a key in some static collection. Then you'd track that session key either through cookies or via hidden input as stated above.

This was a very very useful question to learn more in MVC. Though I got some question like why Microsoft is assuming that people will know TempData uses session.

I got problem with uploading objects more than 4kb. For that our architect suggessted to split that object and save them in chunks in Cookies. I used the code from below blog to split the serialized string of the object.

So split the cookie in the SaveTempData method and collect them into single string in LoadTempData. Thats it problem solved.

But I using a distributed caching technology like NVElocity is always better .

Create a class that looks like this:

public class GlobalStorage
{
    public static Dictionary<string, object> Device = new Dictionary<string, object>();
}

Store:

GlobalStorage.Device.Add("myKey", mydata);

Retrieve:

string mydata = GlobalStorage.Device["myKey"].ToString();
