URL rewrite support for Lighttpd server

I was setting up WordPress permalinks with Lighttpd but encounter some problems: mod_magnet module was not available for the Lighttpd installed on my VPS. It turned out that I need to install the module manually and then restart the server:

user@server$ sudo apt-get install lighttpd-mod-magnet
user@server$ sudo lighty-enable-mod magnet
user@server$ sudo /etc/init.d/lighttpd force-reload

For the permalink to work I did the following. Add this piece of code to /etc/lighttpd/lighttpd.conf

$HTTP["host"] == "dev.sudhaker.com" {
    server.document-root = "/sites/sudhaker.com/htdocs"
    magnet.attract-physical-path-to = ( server.document-root + "/rewrite.lua" )
}

And then

attr = lighty.stat(lighty.env["physical.path"])

if (not attr) then
lighty.env["uri.path"] = "/index.php"
lighty.env["physical.rel-path"] = lighty.env["uri.path"]
lighty.env["physical.path"] = lighty.env["physical.doc-root"] .. lighty.env["physical.rel-path"]
end

to the rewrite.lua under the server document root directory and it should be up and running.
