Reason Phrase

Description

AppOffline

A service unavailable error occurred (an HTTP error 503). The service is not available because application errors caused the application to be taken offline.

AppPoolTimer

A service unavailable error occurred (an HTTP error 503). The service is not available because the application pool process is too busy to handle the request.

AppShutdown

A service unavailable error occurred (an HTTP error 503). The service is not available because the application shut down automatically in response to administrator policy.

BadRequest

A parse error occurred while processing a request.

Connection_Abandoned_By_AppPool

A worker process from the application pool has quit unexpectedly or orphaned a pending request by closing its handle.

Connection_Abandoned_By_ReqQueue

A worker process from the application pool has quit unexpectedly or orphaned a pending request by closing its handle. Specific to Windows Vista and Windows Server 2008.

Connection_Dropped

The connection between the client and the server was closed before the server could send its final response packet. The most common cause of this behavior is that the client prematurely closes its connection to the server.

Connection_Dropped_List_Full

The list of dropped connections between clients and the server is full. Specific to Windows Vista and Windows Server 2008.

ConnLimit

A service unavailable error occurred (an HTTP error 503). The service is not available because the site level connection limit has been reached or exceeded.

Connections_Refused

The kernel NonPagedPool memory has dropped below 20MB and http.sys has stopped receiving new connections

Disabled

A service unavailable error occurred (an HTTP error 503). The service is not available because an administrator has taken the application offline.

EntityTooLarge

An entity exceeded the maximum size that is permitted.

FieldLength

A field length limit was exceeded.

Forbidden

A forbidden element or sequence was encountered while parsing.

Header

A parse error occurred in a header.

Hostname

A parse error occurred while processing a Hostname.

Internal

An internal server error occurred (an HTTP error 500).

Invalid_CR/LF

An illegal carriage return or line feed occurred.

LengthRequired

A required length value was missing.

N/A

A service unavailable error occurred (an HTTP error 503). The service is not available because an internal error (such as a memory allocation failure) occurred.

N/I

A not-implemented error occurred (an HTTP error 501), or a service unavailable error occurred (an HTTP error 503) because of an unknown transfer encoding.

Number

A parse error occurred while processing a number.

Precondition

A required precondition was missing.

QueueFull

A service unavailable error occurred (an HTTP error 503). The service is not available because the application request queue is full.

RequestLength

A request length limit was exceeded.

Timer_AppPool

The connection expired because a request waited too long in an application pool queue for a server application to dequeue and process it. This timeout duration is ConnectionTimeout. By default, this value is set to two minutes.

Timer_ConnectionIdle

The connection expired and remains idle. The default ConnectionTimeout duration is two minutes.

Timer_EntityBody

The connection expired before the request entity body arrived. When it is clear that a request has an entity body, the HTTP API turns on the Timer_EntityBody timer. Initially, the limit of this timer is set to the ConnectionTimeout value (typically 2 minutes). Each time another data indication is received on this request, the HTTP API resets the timer to give the connection two more minutes (or whatever is specified in ConnectionTimeout).

Timer_HeaderWait

The connection expired because the header parsing for a request took more time than the default limit of two minutes.

Timer_MinBytesPerSecond

The connection expired because the client was not receiving a response at a reasonable speed. The response send rate was slower than the default of 240 bytes/sec.

Timer_ReqQueue

The connection expired because a request waited too long in an application pool queue for a server application to dequeue. This timeout duration is ConnectionTimeout. By default, this value is set to two minutes. Specific to Windows Vista and Windows Server 2008.

Timer_Response

Reserved. Not currently used.

URL

A parse error occurred while processing a URL.

URL_Length

A URL exceeded the maximum permitted size.

Verb

A parse error occurred while processing a verb.

Version_N/S

A version-not-supported error occurred (an HTTP error 505).

注冊表值

說明

EnableErrorLogging

DWORD 您可以設置為 TRUE 來啟用錯誤日志記錄或 FALSE 禁用它。默認值為 TRUE。

ErrorLogFileTruncateSize

一個 dword 值，指定一個錯誤日志文件的最大大小以字節為單位）。 默認值為 1 MB （0x100000）。

注意指定的值不能小于默認值。

ErrorLoggingDir

一個 字符串，用于指定 HTTP API 將其日志記錄的文件放入該文件夾。

HTTP API 中指定的文件夾中創建子文件夾 HTTPERR，然后將日志文件存儲在子文件夾。 此子文件夾和日志文件收到相同的權限設置。在管理員和本地系統帳戶擁有完全訪問權限。其他用戶不具有訪問權限。

以下是在注冊表中未指定該文件夾時的默認文件夾：
%SystemRoot%\\System32\\LogFiles

注意ErrorLoggingDir 字符串值必須是完全限定的路徑。但是，它可以包含 %systemroot%。
