I am getting different behavior when using the async upload in SSL. In SSL, It errors and gives a 413 error for any file that is over 1 MB. When I try it on a non ssl area, the file uploads fine. Are there different settings under SSL that's preventing me from uploading larger files? If so how do I change them?

Here's the code I'm using.

var fileExtention = args.get_fileName().substring(args.get_fileName().lastIndexOf('.') + 1, args.get_fileName().length);

if (args.get_fileName().lastIndexOf('.') != -1) {//this checks if the extension is correct

// if (sender.get_allowedFileExtensions().indexOf(fileExtention)) {

function OnClientFileUploadFailed(sender, args) {

if (args.get_message() == "error") {

args.set_handled(true);

}

function submitPage() {

//finds all file uploads that are currently in progress

var isUploadComplete = true;

var uploadingRows = $(".RadAsyncUpload").find(".ruUploadProgress");

//iterates and checks is there any file uploads that are successfully completed or failed and if yes - pop-up an alert box and prevent page submitting

for (var i = 0; i < uploadingRows.length; i++) {

if (!$(uploadingRows[i]).hasClass("ruUploadCancelled") && !$(uploadingRows[i]).hasClass("ruUploadFailure") && !$(uploadingRows[i]).hasClass("ruUploadSuccess")) {

Hi Brad,

I deployed your project from your support ticket on IIS and test it under https and everything is working fine. I was able to upload files bigger than 2MB. There are no different settings that are applied under SSL. In order to narrow down the issue could you try to deploy your project on other IIS server and test it. In case that is working fine the problem should be caused by some IIS setting. To avoid duplication of the threads, please continue the discussion in only one of them.
