Hi,
i cannot run vhosts with lighttpd. I have followed the guide from library.linode.com. But it didn't work for my vhost.
So, I have tried other examples those I found from the internet.
In all case I had the common problem.
Vhosts load files from the server.document-root path from lighttpd.conf file, but not the host-specified path.

here are the configuration files

Please, Help me to find my mistake ..

lighttpd.conf

# Debian lighttpd configuration file

You can't use conditional and simple vhost at once. Check the docs:

http://redmine.lighttpd.net/projects/li ... impleVhost

Well, you can, kinda. simple_vhost makes a darned good default, but I've found I've occasionally needed to throw exceptions in. You can do this by wrapping the entirety of the simple_vhost stuff in a conditional $HTTP["host"] !~ "whatever", then do $HTTP["host"] == "whatever" to match the exceptions. But that's neither here nor there.

The original poster probably wants something like this:

server.modules += ( "mod_simple_vhost" )

simple-vhost.server-root         = "/web"
simple-vhost.document-root       = "public"
simple-vhost.default-host        = "default.example.com"

And then put the content in directories under /web:

/web/example.com/public/
/web/l.example.com/public/
/web/example2.com/public/
/web/default.example.com/public/

... with /web/default.example.com/public/ being the default should the requested hostname not be found in /web.

The trick about simple_vhost is that it is entirely based upon the existence of directories under simple-vhost.server-root. You can add and remove directories on the fly and simple-vhost will adjust accordingly without lighttpd needing to be restarted. That's what makes it simple.

thank you for your respond.
i have faced a lot of issue with lighttpd. When i first setup it worked perfectly but when I installed mono, php and so on vhosts started not to work. And I couldn't find my mistake. I dont know even if i had
So, I return apache back.. Now everything works perfectly.
