I used to get the same problem on the client end from an embedded web server
I developed. Here's what I learned:
1. It only happened when I was serving up binary files from disk.
2. The byte[] buffer I was using was either too big or too small. 1024
worked best.
3. I had problems when using both an OutputStream and a DataOutput stream
together to send data back to the browser. To solve it, I had to do 2
things. 1) Use OutputStream.print() instead of
DataOutputStream.writeChars() when sending binary data. 2) Always flush
before switching from one stream type to another.
Check out the attached code snippet. It's got comments that explain it all
inline. Whenever the browser showed a "Connection reset by peer" message,
it was accompanied by a "Socket write failed" message on the server side.
The changes mentioned above fixed all that.
Make sure also that you set the "Content-Type" header to
"application/octet-stream" when sending binary data. I don't know if you're
sending binary data (such as graphics) files like I was, but if you are,
then I hope this helps.
