the following code called once second. appears work first time fails on subsequent calls java.netconnectexception etimedout. receiving device microchip wifi module 1 port.

private void senddata() {     new thread() {         @override         public void run() {             try {                 socket socket = null;                 dataoutputstream dataout = null;                 try {                     if (socket == null) {                         socket = new socket("1.2.3.4", 2000);                     }                     dataout = new dataoutputstream(socket.getoutputstream());                     dataout.writeutf(datastring());                     l.d("send");                 } catch (unknownhostexception e) {                     e.printstacktrace();                  } catch (ioexception e) {                     e.printstacktrace();                 } {                     if (socket != null) {                         try {                             socket.close();                             l.d("skt close");                         } catch (ioexception e) {                             e.printstacktrace();                         }                     }                 }                  if (dataout != null) {                     try {                         dataout.close();                     } catch (ioexception e) {                         // todo auto-generated catch block                         e.printstacktrace();                     }                 }             } catch (exception e) {                 log.d("exception in thread", e.getstacktrace() + "");             }         }     }.start(); }

amazon web services - S3 Pre-signed POST validate file type? -

i know it's possible put limit on file size content-length-range header. possible validate file type? https://docs.aws.amazon.com/amazons3/latest/dev/httppostforms.html#policyconditions i see there content-type header, if set say, audio/mp3 allow mp3 files , return error if file not mp3? i found previous question answers mention validating file size: s3 direct upload restricting file size , type you can specify content-type @ post request. you can specify @ signature, post must done content-type: { "expiration": "2007-12-01t12:00:00.000z", "conditions": [ {"acl": "public-read" }, {"bucket": "johnsmith" }, {"content-type: "audio/mp3"} ] } creating html form (using aws signature version 4) edit: @ previous question found, checking content-type.
