This module is contained in the mod_log_common.c
file, and is compiled in by default. It provides for logging of
the requests made to the server using the Common Logfile
Format. This module has been replaced by mod_log_config in
Apache 1.2
Log file format
The log file contains a separate line for each request. A line
is composed of several tokens separated by spaces:
host ident authuser date request status bytes
If a token does not have a value then it is represented by a
hyphen (-). The meanings and values of these tokens are as
follows:
host
The fully-qualified domain name of the client, or its IP
number if the name is not available.
ident
If IdentityCheck is
enabled and the client machine runs identd, then this is the
identity information reported by the client.
authuser
If the request was for an password protected document,
then this is the userid used in the request.
date
The date and time of the request, in the following format:
date = [day/month/year:hour:minute:second
zone]
day = 2*digit
month = 3*letter
year = 4*digit
hour = 2*digit
minute = 2*digit
second = 2*digit
zone = (`+' | `-') 4*digit
request
The request line from the client, enclosed in double
quotes (").
status
The three digit status code returned to the client.
bytes
The number of bytes in the object returned to the client,
not including any headers.
A program to receive the agent log information on its
standard input. Note the a new program will not be started
for a VirtualHost if it inherits the TransferLog from the
main server. See, just as an example, cronolog.
Security: if a program is used, then it will
be run under the user who started httpd. This will be root if
the server was started by root; be sure that the program is
secure.
Security: See the security tips document
for details on why your security could be compromised if the
directory where logfiles are stored is writable by anyone other
than the user that starts the server.
