Extended Log Format
Extended Log Format
The extended log file combines the functions of the access log and the error log files,
recording information concerning requests and errors. This format places errors in
context with the relevant request.
Extended Log Entry Format
An entry in the extended log file consists of a single line of ASCII text. Each entry
consists of the tag log followed by one or more items composed of an item-name
and an item-value:
log {item-name1 item-value1} {item-name2 item-value2} ...
404 Not found. The requested object cannot be found on the server, or access
was denied. For example, the WebServer configuration might restrict
access to this region; several configuration commands have a -noexist
option, causing the server to report that the file was not found, rather than
that access was denied.
405 Method not allowed. The request specifies a method not permitted for this
resource.
406 Not acceptable. The requested resource does not comply with the
characteristics specified in the Accept headers. For example, the content
is not available in the requested language.
412 Precondition failed. The requested resource did not meet a condition
specified in one or more request headers, for example If-Modified-Since.
413 Request entity too large. The server cannot process the request.
416 Requested range not satisfiable. The range specified in the request does
not exist in the resource; for example, the starting position of a byte range
specification has a value greater than the length of the requested
resource.
417 Expectation failed. A condition specified in the Expect header cannot be
satisfied by the server.
420 Security retry. The Secure HTTP enhancements on the request were not
acceptable to the server, but a retry with different enhancements might be.
421 Bogus header. A Secure HTTP request was not formed properly.
500 The server encountered an internal error while processing the web client’s
request. An internal error usually involves a configuration problem or a
CGI script returning an error.
501 Not implemented. The request cannot be performed by the server.
505 HTTP version not supported. The request specifies a protocol version that
the server does not support.
