The information in this article applies to:
- Microsoft Internet Information Server 4.0
This article was previously published under Q193419 We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site: SYMPTOMS
If you set the following registry setting:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W3SVC\Parameters
\ReplyWithHTTP1.1 REG_DWORD to 0 (zero)
Internet Information Server (IIS) 4.0 will still use HTTP 1.1 features
(such as chunked transfer encoding). This may cause problems on the client
such as TCP connections remaining open that the client assumes will be
closed, and the client displaying the chunk lengths as part of the HTML
(because it is not expecting chunked content from a 1.0 server).
RESOLUTIONTo resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the
