Thread: File upload problem

Greetings,

I have a problem with uploading of big files.
I have simple html form on client side.
On server side a have a servlet that processes multipart requests with commons-fileupload library. I set max request size :

		DiskFileItemFactory factory = new DiskFileItemFactory();
		ServletFileUpload upload = new ServletFileUpload(factory);
                upload.setSizeMax(maxRequestSize);
		upload.setFileSizeMax(maxRequestSize);

So, if the file is too big

                upload.parseRequest(request);

throws an exception.

The problem is:
When uploaded file is too big servlet throws SizeLimitExceededException and finishes his work very quickly but on client side form submit continues and I have to wait several minutes until it ends. Why this is happened? And how can I cancel client form submit when servlet throws an exception?

I use JBoss 4.2.3 and commons-fileupload-1.2.2.

Thanks in advance

How well a 413+close works depends on your web framework's support for close-after-response and the way your client reacts to a closed connection. It may be that the client will not read the response until the request has finished, in which case closing the connection mid-request will prevent your client seeing the 413 response. It might not be too bad if you were to use scripts to upload files, but on a form submit I think closing the connection would be catastrophic.
