# 'Main' server configuration
#
# The directives in this section set up the values used by the 'main'
# server, which responds to any requests that aren't handled by a
# definition. These values also provide defaults for
# any containers you may define later in the file.
#
# All of these directives may appear inside containers,
# in which case these default settings will be overridden for the
# virtual host being defined.
#
#
# ServerAdmin: Your address, where problems with the server should be
# e-mailed. This address appears on some server-generated pages, such
# as error documents. e.g. admin@your-domain.com
#
ServerAdmin {$global_site_email}
#
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
#

# DocumentRoot: The directory out of which you will serve your
# documents. By default, all requests are taken from this directory, but
# symbolic links and aliases may be used to point to other locations.
#
DocumentRoot "/usr/local/apachemodsecurity"
#
# Each directory to which Apache has access can be configured with respect

# #
# # Possible values for the Options directive are "None", "All",
# # or any combination of:
# # Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews

# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a

# container, that host's errors will be logged there and not here.

ErrorLog "/var/log/httpd-error.log"
#
# LogLevel: Control the number of messages logged to the error_log.
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
#

#
# The following directives define some format nicknames for use with
# a CustomLog directive (see below).
#
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined

#
# The location and format of the access logfile (Common Logfile Format).
# If you do not define any access logfiles within a
# container, they will be logged here. Contrariwise, if you *do*
# define per- access logfiles, transactions will be
# logged therein and *not* in this file.
#
#CustomLog "/var/log/httpd-access.log" common
#
# If you prefer a logfile with access, agent, and referer information
# (Combined Logfile Format) you can use the following directive.
#
CustomLog "/var/log/httpd-access.log" combined
#
# #
# # Redirect: Allows you to tell clients about documents that used to
# # exist in your server's namespace, but do not anymore. The client
# # will make a new request for the document at its new location.
# # Example:
# # Redirect permanent /foo http://www.example.com/bar
#
# #
# # Alias: Maps web paths into filesystem paths and is used to
# # access content that does not live under the DocumentRoot.
# # Example:
# # Alias /webpath /full/filesystem/path
# #
# # If you include a trailing / on /webpath then the server will
# # require it to be present in the URL. You will also likely
# # need to provide a section to allow access to
# # the filesystem path.
#
# #
# # ScriptAlias: This controls which directories contain server scripts.
# # ScriptAliases are essentially the same as Aliases, except that
# # documents in the target directory are treated as applications and
# # run by the server when requested rather than as documents sent to the
# # client. The same rules about trailing "/" apply to ScriptAlias
# # directives as to Alias.
# #
# ScriptAlias /cgi-bin/ "/usr/local/www/apache22/cgi-bin/"

# DefaultType: the default MIME type the server will use for a document
# if it cannot otherwise determine one, such as from filename extensions.
# If your server contains mostly text or HTML documents, "text/plain" is
# a good value. If most of your content is binary, such as applications
# or images, you may want to use "application/octet-stream" instead to
# keep browsers from trying to display binary files as though they are
# text.
#
DefaultType text/plainm
#
# TypesConfig points to the file containing the list of mappings from
# filename extension to MIME-type.
#
TypesConfig etc/apache22/mime.types
#
# AddType allows you to add to or override the MIME configuration
# file specified in TypesConfig for specific file types.
#
#AddType application/x-gzip .tgz
#
# AddEncoding allows you to have certain browsers uncompress
# information on the fly. Note: Not all browsers support this.
#
#AddEncoding x-compress .Z
#AddEncoding x-gzip .gz .tgz
#
# If the AddEncoding directives above are commented-out, then you
# probably should define those extensions to indicate media types:
#
AddType application/x-compress .Z
AddType application/x-gzip .gz .tgz
#
# AddHandler allows you to map certain file extensions to "handlers":
# actions unrelated to filetype. These can be either built into the server
# or added with the Action directive (see below)
#
# To use CGI scripts outside of ScriptAliased directories:
# (You will also need to add "ExecCGI" to the "Options" directive.)
#
#AddHandler cgi-script .cgi
# For type maps (negotiated resources):
#AddHandler type-map var
#
# Filters allow you to process content before it is sent to the client.
#
# To parse .shtml files for server-side includes (SSI):
# (You will also need to add "Includes" to the "Options" directive.)
#
#AddType text/html .shtml
#AddOutputFilter INCLUDES .shtml
#
# The mod_mime_magic module allows the server to use various hints from the
# contents of the file itself to determine its type. The MIMEMagicFile
# directive tells the module where the hint definitions are located.
#
#MIMEMagicFile etc/apache22/magic
#
# Customizable error responses come in three flavors:

#ErrorDocument 404 "/cgi-bin/missing_handler.pl"
#ErrorDocument 402 http://www.example.com/subscription_info.html
