Module asis_module mod_asis.o

Module imap_module mod_imap.o

Module action_module mod_actions.o

## Optional modules for NCSA user-agent/referer logging compatibility

## We recommend, however, that you migrate to the configurable logging

## module, below.

# Module agent_log_module mod_log_agent.o

# Module referer_log_module mod_log_referer.o

## This is a *replacement* for mod_log_common which supports a

## LogFormat directive which allows you to specify what goes into 

## the TransferLog (if you want Referer, etc.) source code for docs.

##

## If you play with this, remember to drop the standard

## mod_log_common --- a server with both will work, but you'll get

## very confused trying to figure out what's going on...

# Module config_log_module mod_log_config.o

## cern_meta mimicks the behavior of the CERN web server with regards to 

## metainformation files. 

# Module cern_meta_module mod_cern_meta.o

## The status module allows the server to display current details about 

## how well it is performing and what it is doing. Consider also enabling 

## -DSTATUS (see the CFLAGS section near the start of the file) to allow

## full status information. Check conf/access.conf on how to enable this.

# Module status_module mod_status.o

## The Info module displays configuration information for the server and 

## all included modules. It's very useful for debugging.

# Module info_module mod_info.o

## Optional authentication modules. 

##

## The anon_auth module allows for anonymous-FTP-style username/ 

## password authentication.

# Module anon_auth_module mod_auth_anon.o

## db_auth and dbm_auth work with Berkeley DB files - make sure there

## is support for DBM files on your system. You may need to grab the GNU

## "gdbm" package if not.

# Module db_auth_module mod_auth_db.o

# Module dbm_auth_module mod_auth_dbm.o

## msql_auth checks against an MSQL database. You must have MSQL installed

## and an "msql.h" available for this to even compile. Additionally,

## you may need to add a couple entries to the CFLAGS line, like

##

## -lmsql -L/usr/local/lib -L/usr/local/Minerva/lib

##

## This depends on your installation of MSQL.

# Module msql_auth_module mod_auth_msql.o

## "digest" implements HTTP Digest Authentication rather than the less 

## secure Basic Auth used by the other modules.

# Module digest_module mod_digest.o

## Outright experiments --- mod_dld defines commands which

## allows other modules to be loaded in at runtime, and mod_cookies

## uses Netscape cookies to automatically construct and log accurate

## click-trails from Netscape cookies, for Netscape-using clients who

## aren't coming in via proxy. 

# Module dld_module mod_dld.o

# Module cookies_module mod_cookies.o

## Finally, the proxy module. It's not as complete as it could

## be yet, so use at your own risk.

# Module proxy_module mod_proxy.o</FONT></PRE>

# for instructions.

# Do NOT simply read the instructions in here without understanding

# what they do, if you are unsure consult the online docs. You have been

# warned. 

# Originally by Rob McCool

# ServerType is either inetd, or standalone.

ServerType standalone

# If you are running from inetd, go to &quot;ServerAdmin&quot;.

# Port: The port the standalone listens to. For ports &lt; 1023, you will

# need httpd to be run as root initially.

Port 80

# HostnameLookups: Log the names of clients or just their IP numbers

# e.g. www.apache.org (on) or 204.62.129.132 (off)

HostnameLookups on

# If you wish httpd to run as a different user or group, you must run

# httpd as root initially and it will switch. 

# User/Group: The name (or #number) of the user/group to run httpd as.

# On SCO (ODT 3) use User nouser and Group nogroup

User nobody

Group #-1

# ServerAdmin: Your address, where problems with the server should be

# e-mailed.

ServerAdmin [e-mail]

# ServerRoot: The directory the server's config, error, and log files

# are kept in

ServerRoot /usr/local/etc/httpd

# BindAddress: You can support virtual hosts with this option. This option

# is used to tell the server which IP address to listen to. It can either

# contain &quot;*&quot;, an IP address, or a fully qualified Internet domain name.

# See also the VirtualHost directive.

#BindAddress *

# ErrorLog: The location of the error log file. If this does not start

# with /, ServerRoot is prepended to it.

ErrorLog logs/error_log

# TransferLog: The location of the transfer log file. If this does not

# start with /, ServerRoot is prepended to it.

TransferLog logs/access_log

# PidFile: The file the server should log its pid to

PidFile logs/httpd.pid

# ScoreBoardFile: File used to store internal server process information

ScoreBoardFile logs/apache_status

# ServerName allows you to set a host name which is sent back to clients for

# your server if it's different than the one the program would get (i.e. use

# &quot;www&quot; instead of the host's real name).

#

# Note: You cannot just invent host names and hope they work. The name you 

# define here must be a valid DNS name for your host. If you don't understand

# this, ask your network administrator.

#ServerName new.host.name

# CacheNegotiatedDocs: By default, Apache sends Pragma: no-cache with each

# document that was negotiated on the basis of content. This asks proxy

# servers not to cache the document. Uncommenting the following line disables

# this behavior, and proxies will be allowed to cache the documents.

#CacheNegotiatedDocs

# Timeout: The number of seconds before receives and sends time out

# n.b. the compiled default is 1200 (20 minutes !)

Timeout 400

# KeepAlive: The number of Keep-Alive persistent requests to accept

# per connection. Set to 0 to deactivate Keep-Alive support

KeepAlive 5

# KeepAliveTimeout: Number of seconds to wait for the next request

KeepAliveTimeout 15

# Server-pool size regulation. Rather than making you guess how many

# server processes you need, Apache dynamically adapts to the load it

# sees --- that is, it tries to maintain enough server processes to

# handle the current load, plus a few spare servers to handle transient

# load spikes (e.g., multiple simultaneous requests from a single

# Netscape browser).

# It does this by periodically checking how many servers are waiting

# for a request. If there are fewer than MinSpareServers, it creates

# a new spare. If there are more than MaxSpareServers, some of the

# spares die off. These values are probably OK for most sites ---

MinSpareServers 5

MaxSpareServers 10

# Number of servers to start --- should be a reasonable ballpark figure.

StartServers 5

# Limit on total number of servers running, i.e., limit on the number

# of clients who can simultaneously connect --- if this limit is ever

# reached, clients will be LOCKED OUT, so it should NOT BE SET TOO LOW.

# It is intended mainly as a brake to keep a runaway server from taking

# Unix with it as it spirals down...

MaxClients 150

# MaxRequestsPerChild: the number of requests each child process is

# allowed to process before the child dies.

# The child will exit so as to avoid problems after prolonged use when

# Apache (and maybe the libraries it uses) leak. On most systems, this

# isn't really needed, but a few (such as Solaris) do have notable leaks

# in the libraries.

MaxRequestsPerChild 30

# Proxy Server directives. Uncomment the following line to

# enable the proxy server:

#ProxyRequests On

# To enable the cache as well, edit and uncomment the following lines:

#CacheRoot /usr/local/etc/httpd/proxy

#CacheSize 5

#CacheGcInterval 4

#CacheMaxExpire 24

#CacheLastModifiedFactor 0.1

#CacheDefaultExpire 1

#NoCache adomain.com anotherdomain.edu joes.garage.com

# Listen: Allows you to bind Apache to specific IP addresses and/or

# ports, in addition to the default. See also the VirtualHost command

#Listen 3000

#Listen 12.34.56.78:80

# VirtualHost: Allows the daemon to respond to requests for more than one

# server address, if your server machine is configured to accept IP packets

# for multiple addresses. This can be accomplished with the ifconfig 

# alias flag, or through kernel patches like VIF.

# Any httpd.conf or srm.conf directive may go into a VirtualHost command.

# See alto the BindAddress entry.
