MVC lose session state?
Please forgive me for my poor English. This is driving me crazy. I'm writing an application in ASP.NET MVC. Basically I have some pages which require to use session state. But now the session state loses after the following code:开发者_如何学编程
...
Session["admin_ID"] = "aa27ec10-d9d4-43d9-96f6-7cfb0d5099ca";
...
After the following code, session states loses:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult GenerateVerifyModel(FormCollection formCollection)
{
...
return File(zipPath, "application/x-zip-compressed");
}
Other code works very well and session state does not lose.
Any suggestion will be appreciated.
Shot in the dark: If you set something in the session and return a file, maybe the HTTP headers doesn't carry session's information... explaining the lost of the session on subsequent calls. But I would doubt it. Pretty hard to tell without a clearer scenario!
Thanks
