Internet Explorer 6 does not display XHTML strict Web pages correctly
This article has been archived. It is offered "as is" and will no longer be updated.
Consider the following scenario:
- You develop a Web page that uses Gzip HTTP compression or Deflate HTTP compression.
- The Web page is hosted on a server that uses Gzip or Deflate compression.
- You use Microsoft Internet Explorer 6 to browse the XHTML strict Web pages on a computer that is running Windows XP Service Pack 2 (SP2).
This problem occurs if one or more of the following conditions are true:
- The size of the HTTP header is too large.
- The computer's workload is high.
This problem occurs because, when Gzip or Deflate compression is used by Internet Explorer 6 on a Windows XP SP2-based computer, Internet Explorer 6 may try to determine the MIME type of an XHTML document before Internet Explorer 6 receives enough data to distinguish between XML and XHTML.
If the first chunk of body content that Internet Explorer 6 receives contains only XML content, the MIME determination may report that the document is "text/xml" instead of "text/html." Therefore, Internet Explorer does not display the XHTML page correctly.
