Hi,

we experienced some differences with IE and Firefox with Flash. If I upload a file with IE the upload speed is half as fast as the upload speed with Firefox. I also can reproduce this with your demo for big file uploads.

If we set the AjaxUploader to IFrame, the speed is almost the same.

We dont have Silverlight installed.

The problem with IFrame is, that we want to calculate and show our own progress in the CuteWebUI_AjaxUploader_OnProgress function but this does not work in IE with IFrame mode. Strangely enough in Firefox this is even working if I set the Uploader to IFrame and disable the Flash Addon.

Another thing is that with IE the calculation of the progress takes more time until it shows up after the upload starts and the time between the progress refresh is higher than with Firefox.

Does the IE have problems with handling flash?

We have IE 9 latest version and Flash 11.5

Thank you

Mark

Hi,

In firefox , the IFrame mode will be converted to HTML5 mode , so you can get the progress information.

IE can't do that because the IE9 do not support the file API

For you case , the IE+Flash may cause some errors, and it will translate to AJAX mode.

You can append ?UploaderDebug=1 to get debug information

Hi,

thanks a lot for the information.

FF was so fast because it switched, like you said, to html5, but if I set the uploader type only to flash then FF isn't faster than IE.

The problem seems to be the HTTPS connection + Flash. If I use only http then the full bandwidth is used, but with https IE and FF with Flash are slow.

Here is the debug output.

Is there any workaround?
