In Windows Server 2008 and later versions, you can also create the following DWORD value under the following registry key: If you experience this issue, you can add the MaxBufferedSendBytes DWORD value to the registry. You may experience slow performance in Internet Information Services (IIS) when Internet Server API (ISAPI) applications or Common Gateway Interface (CGI) applications that are hosted on IIS send responses. If a Server header is present on the response, it will not be removed, if one is not present, it will not be added. A value of 2 will prevent http.sys from appending a Server header to the response. A value of 1 will not append the Server header for responses generated by http.sys (responses ending in 400, 503, and other status codes). A value of 0, which is the default value, will use the header value the application provides to http.sys, or will append the default value of Microsoft-HTTPAPI/2.0 to the response header. This key controls how http.sys behaves with regards to appending the http response header Server for responses that it sends to clients. If zero, it is the length that is bounded by the maximum value of a ULONG. Maximum number of characters in a URL path segment (the area between the slashes in the URL). Any response or fragment that has not been accessed in the number of seconds equal to UriScavengerPeriod is flushed. If nonzero, the Http.sys response and fragment cache are enabled.Īny response that is greater than this value is not cached in the kernel response cache.ĭetermines the frequency of the cache scavenger. If zero, the count bounded by the maximum value of a ULONG. If nonzero, Http.sys accepts the % uNNNN notation in request URLs. If this value is lower than MaxFieldLength, the MaxFieldLength value is adjusted. This limit translates to approximately 32k characters for a URL.ĭetermines the upper limit for the total size of the Request line and the headers. The default value of zero implies that the maximum is computed from available memory. The maximum number of current endpoint objects that are permitted. Overrides the MaxConnections calculation in the driver.

A higher value may enable higher download speeds in network environments that have high bandwidth and high latency. Overrides the TCP window size that is used by Http.sys. If zero (and EnableNonUTF8 is nonzero), Http.sys tries to decode it as ANSI or DBCS if that is not successful, it tries a UTF-8 conversion. If nonzero, Http.sys always tries to decode a URL as UTF-8 first if that conversion fails and EnableNonUTF8 is nonzero, Http.sys then tries to decode it as ANSI or DBCS. If nonzero, Http.sys also accepts ANSI- or DBCS-encoded URLs in requests. If zero, Http.sys accepts only UTF-8-encoded URLs. Setting this registry value may reduce the number of Connections_refused and 503 errors in the Httperr.log file. After you add this value to the registry, the HTTP service stops accepting connections when less than 8 MB of nonpaged pool memory is available. By default, the HTTP service stops accepting connections when less than 20 megabytes (MB) of nonpaged pool memory is available. If nonzero, Http.sys accepts hex-escaped chars in request URLs that decode to U+0000 - U+001F and U+007F - U+009F ranges.

How to back up and restore the registry in Windows. For more information about how to back up and restore the registry, see Then, you can restore the registry if a problem occurs.
For added protection, back up the registry before you modify it. Therefore, make sure that you follow these steps carefully. However, serious problems might occur if you modify the registry incorrectly. This section, method, or task contains steps that tell you how to modify the registry. This article is intended for advanced users and assumes knowledge of the registry and of the risks that are involved when the registry is changed. See the Warning codes section for information about potential risks when you create and configure registry values by using settings other than the default settings. The table in the Registry keys section contains the following information about these registry values:
Several registry values can be configured according to specific requirements.

In Windows Server 2008 and later versions, Http.sys is the kernel mode driver that handles Hypertext Transfer Protocol (HTTP) requests. Original product version: Windows 8, Windows Server 2012, 2008 R2, 2008 This article describes Http.sys registry settings for Windows.
