The jquploader encountered an unexpected error with code #302

/////I utilized this code in two different locations. Initially, I used it in HomeController/Upload action A, and the HTML section in Home/Index.cshtml. The jqUploader functioned properly there. However, when I relocated the codes to use action A in Areas/AdminPanel/Controllers/CarController.cs and the HTML in Areas/AdminPanel/Views/Car/__Extract.cshtml, the jQUploader stopped functioning and an HTTP #302 error was encountered.

////This code functions correctly in a new MVC project. Yet, when attempting to implement it in my project, an error with status code 302 occurs. It seems like it might be related to Global.asax.cs, but I am unsure of how to resolve this issue. Can anyone provide insight into why this problem may be happening?

Answer №1

When your server responds with HTTP Status code 302, it is indicating a redirection to another location. Use tools like firebug to determine the destination and inform me of what you discover. Additionally, consider adding the [HttpPost] attribute to your Upload action.

A common reason for this redirection may be attempting to access admin features without being logged in. This can be confirmed by examining the path Areas/AdminPanel/Views/Car/, which often results in redirection to the login page.

Ensure that the Authorize attribute is included in the Global Filter within Global.asax.cs or placed on top of your Upload action. If already logged in, login again before attempting to upload.

If already authenticated, verify if the jqUploader is sending the necessary auth cookie. Utilize tools such as firebug's net panel XHR tab to inspect these details.
