The socket has been closed by the client (browser).

A bug in your code:

byte[] outputByte=new byte[4096];
while(in.read(outputByte,0,4096)!=-1){
   output.write(outputByte,0,4096);
}

The last packet read, then write may have a length < 4096, so I suggest:

byte[] outputByte=new byte[4096];
int len;
while(( len = in.read(outputByte, 0, 4096 )) > 0 ) {
   output.write( outputByte, 0, len );
}

It's not your question, but it's my answer... ;-)

It seems like your problem may be arising at   while in read outputByte 0 4096   -1    where it might go into an infinite loop for not advancing the offset  which is 0 always in the call    Try   while in read outputByte   -1    which will by default try to read upto outputByte length into the byte    This way you dont have to worry about the offset  See FileInputStrem s read method

I had the same problem with small difference      Exception was raised at the moment of flushing   It is a different stackoverflow issue  The brief explanation was a wrong response header setting   response setHeader  Content-Encoding    gzip     despite uncompressed response data content   So the the connection was closed by the browser

The correct way to  solve  it is to close the connection and forget about the client  The client has closed the connection while you where still writing to it  so he doesn t want to know you  so that s it  isn t it

I ve got the same exception and in my case the problem was in a renegotiation procecess  In fact my client closed a connection when the server tried to change a cipher suite  After digging it appears that in the jdk 1 6 update 22 renegotiation process is disabled by default  If your security constraints can effort this  try to enable the unsecure renegotiation by setting the sun security ssl allowUnsafeRenegotiation system property to true  Here is some information about the process      Session renegotiation is a mechanism within the SSL protocol that   allows the client or the server to trigger a new SSL handshake during   an ongoing SSL communication  Renegotiation was initially designed as   a mechanism to increase the security of an ongoing SSL channel  by   triggering the renewal of the crypto keys used to secure that channel    However  this security measure isn t needed with modern cryptographic   algorithms  Additionally  renegotiation can be used by a server to   request a client certificate  in order to perform client   authentication  when the client tries to access specific  protected   resources on the server    Additionally there is the excellent post about this issue in details and written in  IMHO  understandable language
