java - Amazon sesThrottling – Maximum sending rate exceeded -


as per documentation says, if reach max send rate, error. max send rate 14 emails per second , tried send 100 mails concurrenlty, emails arrived recipient.

so wonder why amazon ses didn't send "signal" complaining excess or easier, why amazon ses did deliver 100 emails when supposed send 14.

here code used:

    list<string> destinations = new arraylist<>(); //replace email addresses      (int = 0; < 100; i++) {         destinations.add("receiver address");     }     int i=0;     (string destination : destinations) {          new thread("" + i){             public void run(){                 system.out.println("thread: " + getname() + " running");                 int maxretries = 10;                 while(maxretries-->0) {                     try {                         // create subject , body of message.                         content subject = new content().withdata("asunto");                         content textbody = new content().withdata("cuerpo");                         body body = new body().withtext(textbody);                          // create message specified subject , body.                         message message = new message().withsubject(subject).withbody(body);                         destination destination2 = new destination().withtoaddresses(new string[]{destination});                         // assemble email.                         sendemailrequest request = new sendemailrequest().withsource("fromnaddres").withdestination(destination2).withmessage(message);                          //wait permit become available                         //ratelimiter.acquire();                          //call amazon ses send message                         sendemailresult result = client.sendemail(request);                         system.out.println("sent "+result.getmessageid());                         break;                     } catch (amazonserviceexception e) {                         //retries throttling errors                         system.out.println("hola");                         if ("throttling".equals(e.geterrorcode())  && "maximum sending rate exceeded.".equals(e.getmessage())) {                             system.out.println("maximum send rate exceeded when sending email "+destination+". "                                     +(maxretries>1?"will retry.":"will not retry.") );                         } else {                             system.out.println("unable send email to: "+destination+". " +e.tostring());                             break;                         }                     } catch(exception e) {                         system.out.println("unable send email to: "+destination+". " +e.tostring());                         break;                     }                 }             }         }.start();          i++;     }

amazon ses gives room or flexibility on either daily message quota , maximum sending rate. don't disclose deviation percentage allowed, find out doing tests.

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
