sockets - Java: measure network bandwidth for a specific code segment -

-

i want add bandwidth measurements servers (written in pure java). thinking of api like

measurebandwidthsignletone.getinstance().startmeasuring(); ...... .....//here may connect db or using http (httpurlconnection)... ..... measurebandwidthsignletone.getinstance().endmeasuring();

problem have many different kinds of code access network (jdbc, httpurlconnection, ftp, etc...) wondering if can somehow attach threadlocal monitor sockets, allow me know how many bytes uploaded or download.

i know 1 way using asm / aspectj change byte code - there simpler way plug in java socket api?

thank you

what setting custom made socketfactoryimpl? can work?

that work specific version of jvm. if know version targeting create modified version of class.

the reason won't work generic jvm class uses internal apis can different between versions why byte code injection more work broad range of jvms.

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/?...
