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

# e-mailed.



ServerAdmin you@your.address



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

# are kept in



ServerRoot /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

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