I am getting the http error1 :405:MethodNotAllowed error after selecting a file. I am getting the error in both IE and Chrome (have not tried other browsers).

Here is my ASPX code, which is put inside an UpdatePanel.

                    <CuteWebUI:UploadAttachments InsertText="Attach" runat="server"
                        ID="Attachments" MultipleFilesUpload="true">
                        <InsertButtonStyle BorderStyle="Groove" />
                    </CuteWebUI:UploadAttachments>

The code works just fine in the built-in webserver of VS2010, but fails with the aforementioned error when deployed to an IIS 6.0 webserver.

Using Fiddler, I have traced the 405 call to  POST to the following URL:

http://servername:5278/?UseUploadModule=Dynamic&_Namespace=CuteWebUI&_UploadID=ContentPlaceHolder_AttachmentsImage_1349954243888_1&_UploadControlID=ctl00$ContentPlaceHolder$Attachments&ContextValue=!3wEWAQUgQzpcV0lORE9XU1xURU1QXEFqYXhVcGxvYWRlclRlbXAhQGyQWFMZ5unan822kkmCWZ9v5MBLw3CIZ8DsNxw7EQ!2!2&_VFN=esm-banner.png&_Addon=verify&_AddonGuid=49b5343e-1362-4fd5-a43d-1f48b4c8ed42 

Is this a problem with the Web Service Extensions in IIS 6.0? The ASP.NET 4 extensions are allowed, and the site runs fine in all other regards.

Thanks! 

Hi,

1. Do you get the same errro with the example page code below?

2. Can you send me your uploader page url and show me the full steps to reproduce this error?

3. Does it happens with all files? Or just special file/size/extension?

Regards,

Ken 

1. The example code works fine, even when placed inside an UpdatePanel. Do you now what differences I should be looking for in my other code to pin-point the cause of it not working there?

2. Sorry, it's an webpage on an internal LAN.

3. All files/sizes/extensions.

Thanks!
