Hi,
Thanks a lots for your reply.
and I'm sorry previous httpd.conf file was typo.

Here is correct one and it works well.
but I sitll want to use lighttpd...
------------------------------------------------
<VirtualHost xxx.xxx.xxx.xxx>
DocumentRoot /var/www/html/davical
DirectoryIndex index.php index.html
ServerName example.sharp.co.jp
Alias /images/ /var/www/html/davical/htdocs/images/
<Location /var/www/html/davical>
DAV on
</Location>
php_value include_path /usr/share/awl/inc
php_value magic_quotes_gpc 0
php_value register_globals 0
php_value error_reporting "E_ALL & ~E_NOTICE"
php_value default_charset "utf-8"
</VirtualHost>
--------------------------------------------------

anyway, I'll check wiki and mailing list.

thanks, Hiroshi HARA.
