< Yaws mailing list ~ virtual server with multiple names |

Greetings,
I'm trying to add a virtual server which has more than one name.
Typically, I want the server to answer to both domain.dom as well as
WWW.domain.dom, and in rare cases, a third or more names as well.
In Apache, one does this with ServerName and ServerAlias, e.g,
<VirtualHost *:80>
ServerName domain.dom
ServerAlias www.domain.dom
</VirtualHost>
Now requests for both those hostnames will be handled by this
VirtualHost directive. What's the equivalent for yaws? I found
'servername' in the docs, but that just seems to override <server
ServerName> rather than extending it.
<server domain.dom>
port = 80
listen = 0.0.0.0
servername = www.domain.dom
</server>
I also tried giving servername a comma separated list, but it didn't like that.

Cheers, L |

You might want to redirect one of the domains to the other instead of
having multiples name for the same site.

I guess that will work. Thanks. Though I wouldn't complain if the
developers added a 'serveralias' directive.

From my guest appearance in the search engine optimization field I know that
having more than one name for the same document is a bad idea.
Inbound links are not focused to one name of the document, and search engines
can suspect duplicate content and deem the document content less relevant.

I agree, using it with redirs is better. This is what I've been
doing for that precise problem with multiple names for the same
domain.
Also noteable here is the configuration directive:
pick_first_virthost_on_nomatch (read in the manpage what it does)
/klacke

Adding vhost alias support is pretty trivial.. heres a quick patch that does
it and includes *.servername.com support
to use it add a serveraliases line in your <server> section specifiying one
or more aliases... eg:
<server servername.com>
serveraliases = *.servername.com
port = 80
docroot = www/
</server>
