Error Log Format
Error Log Format
The error log file records all request and server errors. The information in this file is
structured in the common log format (CLF). CLF is generally used by web servers and
supports a number of widely available tools for analyzing server logs and generating
reports.
The location of the error log file is specified by the ErrorLog directive in the server
configuration file. If this directive is not explicitly set, no error log file is generated.
HyperText Transfer Protocol (HTTP) Status
Codes
Table C-2 lists the HTTP status codes that may appear in the extended log file and in
the access log file.

Status Code Description
100 Continue. The server received the previous part of the request, so the
client should send the next part.
200 Normal result. The request completed without error.
201 Created. A new object was created.
204 No content. The request was processed successfully; the response does
not contain a new document but might contain metainformation to apply to
the current document.
206 Partial content. The server fulfilled a request for a byte range.
301 Moved permanently. The requested resource now resides at a new
location. The request was satisfied by redirection, and any future requests
for the resource should use the new URL.
302 Found/Moved temporarily. The requested resource temporarily resides at a
different location. The request was satisfied by redirection, but any future
requests for the resource should use the original URL.
304 Not modified. The requested object was not modified after the date
specified in the web client’s “If-modified-since” header.
400 Bad request. The web client sent a request the server could not
understand.
401 Unauthorized. The request requires authorization (such as a user name
and password) for access to the requested resource.
403 Forbidden. Access to the requested object is not allowed. For example,
the WebServer configuration might restrict access to this region.
