Yeah, but if you wanna use pure-Ruby/webrick you can use my approach:
require ''webrick''
module WEBrick
# A VHostServer is a HTTPServer that holds several mount tables.
# Each mount table corresponds to a regexp. The mount table to use
# for a request is the first one whose regexp matches the uri in the
# request. This allows for easy "virtual hosting".
class VHostServer < HTTPServer
def initialize(*args)
super
@mount_tables = [] # holds [UriRE, MountTable] pairs
@default_mount_table = @mount_tab
end
def vhost_mount(uriRegexp, dir, servlet, *options)
@logger.debug(sprintf("%s is mounted on %s for %s.", servlet.inspect, dir, uriRegexp.inspect))
re, mt = @mount_tables.detect {|re, mt| re == uriRegexp}
unless mt
mt = MountTable.new
@mount_tables << [ uriRegexp, mt ]
end
mt[dir] = [ servlet, options ]
end
def service(req, res)
if req.unparsed_uri == "*"
if req.request_method == "OPTIONS"
do_OPTIONS(req, res)
raise HTTPStatus::OK
end
raise HTTPStatus::NotFound, "`#{req.unparsed_uri}'' not found."
end
# Only change from HTTPServer#service:
url = req.request_uri.to_s
servlet, options, script_name, path_info = search_servlet(req.path, url)
# ------------------------------------
raise HTTPStatus::NotFound, "`#{req.path}'' not found." unless servlet
req.script_name = script_name
req.path_info = path_info
si = servlet.get_instance(self, *options)
@logger.debug(format("%s is invoked.", si.class.name))
si.service(req, res)
end
def search_servlet(path, url)
mount_table = search_mount_table(url)
script_name, path_info = mount_table.scan(path)
servlet, options = mount_table[script_name]
if servlet
[ servlet, options, script_name, path_info ]
end
end
def search_mount_table(url)
re, mt = @mount_tables.detect {|re, mt| re.match(url) }
mt || @default_mount_table
end
end
end
I just thought it was already in there...
