Using _default_ vhosts
<VirtualHost _default_:*>
DocumentRoot /www/default
...
</VirtualHost>
Using such a default vhost with a wildcard port effectively prevents any
request going to the main server.
A default vhost never serves a request that was sent to an address/port that is
used for name-based vhosts. If the request contained an unknown or no Host:
header it is always served from the primary name-based vhost (the vhost for
that address/port appearing first in the configuration file).
You can use
AliasMatch<http://apache.active-venture.com/mod/mod_alias.html#aliasmatch> or
RewriteRule<http://apache.active-venture.com/mod/mod_rewrite.html#RewriteRule>
to rewrite any request to a single information page (or script).
I got this one from net.
But I am not getting the concept of blue line mentioned above. And what is the
meaning of main server in case of serving request by apache.
Any reply ?
Thanks
