Limit bandwidth per-IP by value from HTTP Header -

-

i have file download site. limiting bandwidth per ip (!). limit should set dynamically http header backend.

my current implementation uses x-accel-limit-rate (i can change header, it's not hard-coded anywhere), limit current connection/request.

is idea doable in g-wan?

yes, can done.

write g-wan handler extract x-accel-limit-rate http header. enforce policy using throttle_reply() g-wan api call documented here.

an example available called throttle.c might further.

the throttle_reply() g-wan function lets apply throttling on global basis or per connection, apply relevant throttling values either ip addresses or authenticated users, depending on needs.

throttle_reply() can change download speed dynamically during lifespan of each connection can slow-down old connections , create new ones adaptive download rate.

of course, can enforced on per client ip address (or cookie, or isp/datacenter record) deal huge workloads.

php - render data via PDO::FETCH_FUNC vs loop -

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...

javascript - Which segment of a polyline was clicked? -

-
i have set sample polyline 5 segments , , i'm allowing new markers created when user clicks on polyline. i'd know if there's foolproof way determine whether new marker between markers 0 , 1, or 1 , 2 ... or between 4 , 5. i've considered checking if new marker inside bounding box, , point-in-line formulas, neither 100% precise. as google maps uses mercator projection projecting gps coordinates, can't use 'line equation' gps coordinates, because projection not linear gps points.but instead can use world coordinates linear. here have used parametric form of line equation check whether point on segment: function ispointonsegment( map, gpspoint1, gpspoint2, gpspoint ){ var p1 = map.getprojection().fromlatlngtopoint( gpspoint1 ); var p2 = map.getprojection().fromlatlngtopoint( gpspoint2 ); var p = map.getprojection().fromlatlngtopoint( gpspoint ); var t_x; var t_y; //parametric form of line equation is: //-...
