Question

I’m developing some website with ASP.Net for uploading and processing some MS word docs. and I get connection was interrupted in Chrome or connection was reset in firefox for uploading docs bigger than 4 MB. I get this error as soon as I push the button and it almost upload nothing.

it’s the part of the code I think causes the error (I use the common input type=file for upload slot)

 if (filMyFile.PostedFile != null)
    {
        // Get a reference to PostedFile object
        HttpPostedFile myFile = filMyFile.PostedFile;

        // Get size of uploaded file
        int nFileLen = myFile.ContentLength;

        // make sure the size of the file is > 0
        if (nFileLen > 0)
        {
            // Allocate a buffer for reading of the file
            byte[] myData = new byte[nFileLen];

            // Read uploaded file from the Stream
            myFile.InputStream.Read(myData, 0, nFileLen);

            // Create a name for the file to store
            string strFilename = Path.GetFileName(myFile.FileName);



            // Write data into a file
            WriteToFile(Server.MapPath(strFilename), ref myData);

where do you think the problem is? thanks

The 4MB is default limit set in machine.config. You can extend upload file limit by adding <httpRuntime/> element in web.config file. For more detail read this post.
