sockets - Continue to use the same connection after receiving [FIN, ACK] -

-

i see servers stop connection once single request done sending [fin, ack]

from wiki,

a connection can "half-open", in case 1 side has terminated end, other has not. side has terminated can no longer send data connection, other side can. terminating side should continue reading data until other side terminates well.

in case want speed requests avoiding repeating handshake per request. possible client keep communicating server terminated end? there response server or server read request without responding?

usually, when terminate write half of tcp connection, means you're done communicating , wait partner (whether it's server, client or equal counterpart) finish it's transmissions. when partner ready, terminates write half , tcp connection closed.

so if server has terminated end, you're still able send data reliably, aren't able receive result.

if don't want handshakes in tcp, why not taking protocol without handshakes? example udp, if messages aren't heavy , intense.

routes - Laravel 4 Wildcard Routing to Different Controllers -

-
realizing i'm going take beating this, have several questions "best practices" when constructing laravel route. do laravel routes run "first come first serve" top bottom? if route found, pass control controller (or perform action) , terminate? i have part of application acts url shortner. so, route looks this: route::get('/{id}', array('as' => 'home.text', 'uses' => 'homecontroller@text'), function($id){ //make sure id exists before pushing controller. if (storage::where('shortcode','=', $id)->count() > 0) { // route found } }); how can improved? one, i'm not sure how pass processing on controller conditionally.. sort of controller::make() ..? 3) there better way in laravel check if record exists versus doing mode::where('column','=','value')->count() 4) have legacy urls http://url.com/?...
