SYMPTOMS

When Microsoft Pocket Internet Explorer sends more than 16 kilobytes (KB) of data to an HTTP server by using the POST method, the operation may indefinitely stop responding. When this problem occurs, the animated browser logo appears and indicates that the page is loading.

CAUSE

Pocket Internet Explorer uses 16 KB buffers. When more than 16 KB of data is sent, the part of the packet that exceeds 16 KB is put in a second buffer. The second buffer may not be sent to the server. This problem occurs because the data calculation incorrectly determines that the packet fit in the first buffer.

WORKAROUND

To work around this problem, break the data that you want to post to the server into small chunks. Make the chunks less than 16 KB each.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
