when store not found in multistore setup, it should redirect properly

[m4mum]

1. Fresh install multistore setup let's say on http://mystore.com
2. Add sub-domain http://store1.mystore.com/ from admin panel
3. Try accessing http://somerandomstore.mystore.com

In index.php, it is not finding somerandomstore url so it is setting store_id as 0 (master store/main store) and all cookies etc set as per main store, but It does not show user about error! (or even not re-directing to main store).

Due to this, all sub-sequent cross domain request set-up (by external module/plugin) is not working!

Reco Behaviour:

1. either show error page/404 etc
2. redirect properly to default/main store.

PS : I have store/dns all setup with this with 1.5.6 version (latest stable) If anyone wants to check more than happy to share details. plz mail on raxit[at] m4mum [dot] com
