uploadify: IO error

Question

I've following code for multiple image upload:

<SCRIPT>

function render_uploadify()
{
    $("#body_partition_middle").html('<DIV class = "photo_upload_w"><DIV class = "photo_upload" id = "photo_upload"></DIV><BR><INPUT id = "photo_upload_input" name = "photo_upload_input" type = "file"/><a href="javascript:$(\'#photo_upload_input\').uploadifyUpload();">Upload Files</a></DIV>');

    $("#photo_upload_input").uploadify({
            "uploader"  : "/knock/js/uploadify/uploadify.swf",
            "script"    : "/knock/dummy/upload.html",
            "cancelImg" : "/knock/js/uploadify/cancel.png",
            "folder"    : "/knock/js/uploads",
            "multi"     : true,
            "queueID"   : "photo_upload",
            "auto"      : true
        });
}

</SCRIPT>

The above function is being called like:

<A href = "javascript:render_uploadify()">Upload</A>

Well, the GUI is rendered buy uploadify plugin but when I try to upload files, it ends up into IO error.

The request that I'm receiving at the backend is like:

POST /knock/dummy/upload.html HTTP/1.1
Host: 192.168.1.2:8888
User-Agent: Shockwave Flash
Connection: Keep-Alive
Cache-Control: no-cache
Accept: text/*
Content-Length: 2492
Content-Type: multipart/form-data; boundary=----------------------------368d2437ab8d

But there is no HTTP request message body.

Could somebody please tell me what I might be doing wrong here!!

Answer 1

Your IIS is limiting the asp request to the default size which is lower than the file you are uploading, I bet it will work for 10k files right now. Check the following link and that will fix it:
