HTML pages only partially appear, HTML pages do not appear at all, or the network stops responding

When Microsoft Internet Explorer receives compressed HTTP data, you may experience one of the following problems:

• HTML pages may only partially appear, or the pages may not appear at all.
• Your HTTP connection may stop responding.

This behavior occurs because Internet Explorer does not read all the data in the HTTP response.

Microsoft has confirmed that this is a problem in Internet Explorer 6.

In Internet Explorer, the Urlmon.dll file uses an internal buffer to read compressed data. Urlmon.dll fills this buffer when more data arrives and empties the buffer when Urlmon�s client, Mshtml, reads data. The bytes that remain to be decoded in the buffer may be small (8 bytes or less) and the data contained in the buffer decompresses to 0 bytes. Frequently, this data is gzip frame data. When Mshtml receives 0 bytes, it thinks that all the data is read and closes the data stream. As a result, the HTML page sometimes appears truncated. Typically, if it is for a referenced file such as a .js or a .css file type, the HTTP connection stops responding. This problem may occur intermittently or consistently, depending on the server configuration. After you apply the hotfix, clear the cache to delete any files that have the incorrect HTTP version.
