so i want to expand my site to have like region site, so when user open my site it will be ask to select which region he/she interested into and lets just say he interesting in London, then the site will generate a webpage that already all content related to that region...

i tried to just do the same way i create administrator page by group them in this route

Route::group(array('prefix'=>'admins','before' => 'auth'),function(){
    Route::resource('partner','AdminPartnerController',array('except' => array('show')));
    Route::get('partner/index_kategori/{id}',array(
        'as' => 'admins.partner.index_kategori',
        'uses' => 'AdminPartnerController@index_kategori'
});

but it's mean that i need to create a different controller function for each region i gonna create, so it's not very efficient.

what comes to my mind is just like making

www.websiteadress.com/region

so how i can catch that "/region" and add that value into each my function in controller? how to build that kind of routes?

update:

to make it more easily to understand, what become my problem is like i have this normal route:

Route::get('product/{id}',array( 'as' => 'product','uses' => 'PublicController@product'));

what this route do is pretty straight foward, when i type

www.websiteadress.com/product/12

it will open the product page for number 12, so my problem is if i add like this

www.websiteadress.com/Asia/product/12 

how i make my PublicController to catch Asia and later in my product function i will just process that..?
