#
#      Therefore, it is possible to add more arguments to the command by specifying them

#      If you need too, you can use a shell script to process the content of /dev/stdin
#      (/dev/stdin is the mail_content passed by Sarg to the script) and call whatever
#      command you like. It is not limited to mailing the report via SMTP.

#      If resolve_ip is active, the IP address is resolved before being looked up in this
#      file. That is, if you want to map the ip address, be sure to set resolve_ip to no or
#      the resolved name will be looked up in the file instead of the IP address. Note that
#      it can be used to resolve any IP address known to the DNS and then map the unresolved
#      IP addresses to a name found in the usertab file.
#      Table syntax:

#      Saves the processed log in a Sarg format after parsing the squid log file.
#      This is a way to dump all of the data structures out, after parsing from

www_document_root /usr/local/www

# TAG: block_it module_url
#     This tag allows you to pass urls from user reports to a cgi or php module,

#
#     Eg.: block_it /sarg-php/sarg-block-it.php
#     sarg-block-it is a php that will append a url to a flat file.
#     You must change /var/www/html/sarg-php/sarg-block-it to point to your file
#     in $filename variable, and chown to the httpd owner.
#
#     Sarg will pass http://module_url?url=url
#
#block_it none

# TAG: external_css_file path
#     Provide the path to an external CSS file to link into the HTML reports instead of
#     the inline CSS written by sarg when this option is not set.
#
#     In versions prior to 2.3, this used to be an absolute file name to
#     a file to include verbatim in each HTML page but, as it takes a lot of
#     space, version 2.3 switched to a link to an external CSS file.
#     Therefore, this option must contain the HTTP server path on which a client
#     browser may find the CSS file.
#
#     Sarg use theses style classes:
#	.logo		logo class
#	.info		sarg information class, align=center
#	.title_c	title class, align=center
#	.header_c	header class, align:center
#	.header_l	header class, align:left
#	.header_r	header class, align:right
#	.text		text class, align:right
#	.data		table text class, align:right
#	.data2		table text class, align:left
#	.data3		table text class, align:center
#	.link  		link class
#
#     Sarg can be instructed to output the internal CSS it inline
#     into the reports with this command:
#
#        sarg --css
#
#     You can redirect the output to a file of your choice and edit
#     it to your liking.
#

# TAG: user_authentication yes|no
#     Allow user authentication in User Reports using .htaccess

# TAG: sorttable path
#      The path to a javascript script to dynamically sort the tables.
#      The path is the link a browser must follow to find the script. For instance,
#      it may be http://www.myproxy.org/sorttable.js or just /sorttable.js if the script
#      is at the root of your web site.
#
#      If the path starts with "../" then it is assumed to be a relative
#      path and Sarg adds as many "../" as necessary to locate the js script from
#      the output directory. Therefore, ../../sorttable.js links to the javascript
#      one level above output_dir.
#
#      If this entry is set, each sortable table will have the "sortable" class set.
#      You may have a look at http://www.kryogenix.org/code/browser/sorttable/
#      for the implementation on which Sarg is based.
#
sorttable /sarg_sorttable.js

# TAG: hostalias
#      The name of a text file containing the host names (one per line) and the
#      optional alias to use in the report instead of that host name.
#      Host names may contain up to one wildcard denoted by a *. The wildcard
#      must not be at the end of the host name.
#      The host name may be followed by an optional alias; if no alias is provided,
#      the host name, including the wildcard, replaces any matching host name found
#      in the log.
#      Host names replaced by identical aliases are grouped together in the
#      reports.
#      IP addresses are supported and accept the CIDR notation both for IPv4 and
#      IPv6 addresses.
#
#      Example:
#      *.gstatic.com
#      mt*.google.com
#      *.myphone.microsoft.com
#      *.myphone.microsoft.com:443 *.myphone.microsoft.com:secure
#      *.freeav.net antivirus:freeav
#      *.mail.live.com
#      65.52.00.00/14 *.mail.live.com
