Example /etc/koha.conf file entries
  
database=Koha
hostname=localhost
user=Koha
pass=xxxxxx
includes=/usr/local/www/koha/htdocs/includes
Please note the final line (includes=path) - The path entry can be used as an alternative to manually editing the path in Output.pm file (see INSTALL manual).

Example apache httpd.conf entries:
Koha makes extensive use of Server Side Includes (SSI):


http://httpd.apache.org/docs/mod/mod_include.html 
If your page headers and footers do not show, then you may need to re-configure your web server.

Here is an example of entries suitable for Apache httpd.conf:


<VirtualHost 111.222.333.1>
   ServerName koha.example.com
   ServerPath /var/www/library
   DocumentRoot /var/www/library/koha/html
   Alias /images/ "/var/www/library/koha/html/images/"
   ScriptAlias  /cgi-bin/koha/ "/var/www/library/koha/cgi-bin/"
   SetEnv PERL5LIB "/var/www/library/modules"
   ErrorLog /var/log/httpd/koha-error_log
   # 
   # ======== koha uses Server Side Includes =========
   # Normally here, use the same path as "DocRoot" above
   <Directory "/var/www/library/koha/html">
        #       
        AllowOverride None
        #
        # First, you MUST enable +Includes or +IncludesNoExec
	#
        Options +Includes -FollowSymlinks -Indexes
        #
        # Second, you must also configure one of following:
	#
        # 1. server-parsed content (SSI) for files ending in ".html"
	#
        AddHandler server-parsed .html
        #
            # ...OR... (not "AND" !!!!)...
            #
            # 2. Allow SSI if executable bit set using "XBitHack"
            # XBitHack on|off|full
            #
            # XBitHack on - any file that has the user-execute bit
            # - set will be treated as a server-parsed html doc. 
            # - The "full" = "on" but, in addition, will test the
            # - group-execute bit. If the group execute bit is set
            # - then the Last-modified date of the returned file
            # - is sent. If group-execute bit is not set, then no
            # - last-modified date is sent.
	    # - Setting this bit allows clients and proxies to
	    # - cache the result of the request!
            #
            # For example, enable XBitHack (on) if you want to
            # - include non-executable content in documents like:
            #   <!--#include virtual="/includes/footer.inc" -->
            #   <!--#include virtual="/cgi-bin/counter.pl" -->
            #
            # XBitHack on
            #
            # Remember - do not use XBitHack if using AddHandler!
    </Directory>    
</VirtualHost>

<VirtualHost 111.222.333.1>
    ServerName opac.example.com
    ServerPath /var/www/library
    DocumentRoot /var/www/library/opac/html
    Alias /images/ "/var/www/library/opac/html/images/"
    ScriptAlias  /cgi-bin/opac/ "/var/www/library/opac/cgi-bin/"
    SetEnv PERL5LIB "/var/www/library/modules"
