I am trying to upload a file in ASP.net MVC and want to give a user a message that "You have exceeded maximum file size" if user exceeds the maximum file size but when I try to upload a large file it gives me Httpstatus code as 200 when i checked IIS logs there are 2 request logged in IIS one is HttpStatusCode 302 and another as 200.I am not doing any kind of redirect but IIS logs are giving me 302.How can I generate 404.13 error for these kind of request and how can I track this error so that I can give a meaningful message.
Using the HTML5 File API,
var size = document.getElementById('myFile').files[0].size;
Try this plugin Blueimp jquery file upload
u can see the plugin configuration here.it has an option of setting the max file size so that u can alert the user before a server round-trip.

We are trying to download attachments from RingCentral (Glip), however, we have noticed that the download URL has been changed during the last couple of days. We have tried using the Bearer Token with the new download URL to download the files, however, we have received an error with response code 503.

The request could not be satisfied.
The Lambda function associated with the CloudFront distribution is invalid or doesn't have the required permissions. We can't connect to the server for this app or website at this time. There might be too much traffic or a configuration error. Try again later, or contact the app or website owner.

The only change necessary for the recent auth change is to add the Bearer Token to the URL. This can be seen in the update notice:
What do I need to do?
To eliminate or minimize the impact of this change, developers will need to modify their application to attach authentication credentials to all file download requests. See downloading protected content in the Media content section of the RingCentral Developer Guide.

A 503 HTTP Status Code is a temporary sever-side error so there's generally nothing to be done on your end but the problem should go away on its own. If you cannot wait or it's taking a long time to resolve itself, please create a support case so the team can communicate the status to you.
Here's some information on 503 errors from MDN:
503 Service Unavailable
The HyperText Transfer Protocol (HTTP) 503 Service Unavailable server error response code indicates that the server is not ready to handle the request.
Common causes are a server that is down for maintenance or that is overloaded. This response should be used for temporary conditions and the Retry-After HTTP header should, if possible, contain the estimated time for the recovery of the service.
Caching-related headers that are sent along with this response should be taken care of, as a 503 status is often a temporary condition and responses shouldn't usually be cached.
I have an image upload tool and I want to report an error before the file is uploaded if the size is too large for my server.
Is there a c# ASP .NET MVC 5 command for finding out this size?
I don't know if it makes a difference but i'm hosted with Microsoft Azure.
You server application can to know this value, by reading Web.config:
var section = ConfigurationManager.GetSection("system.web/httpRuntime") as HttpRuntimeSection;
// Value in KBs. 4096 means 4Mb.
var maxRequestLength = section.MaxRequestLength;
You'd have to write a controller action that queried the IIS configuration and returned the value to the client.
The client would need to call this method to find out the limit before attempting the upload.
A way to find out the value is described here:

in my ASP.Net MVC 3 application I have uploading images logic. How can I find out is some file that user try to upload realy an image? I need to check it before uploading , on client side
If you use:
Image.FromStream(stream)
it will throw an ArgumentException if it is not a valid image.
I have a custom ASP.Net server in a WinForms application. The server was created using CreateApplicationHost and a simple HttpWorkerRequest implementation.
I find that the custom server only processes requests for aspx files. If I try to access xml / txt / png files from the browser, it gives a "The resource cannot be found." error.
My question is: what must be done to be able to serve such files?
The answer is that the HttpWorkerRequest.SendResponseFromFile method must be overridden to send the file via the response stream.
