Q: 

Does HttpsURLConnection.getOutputStream() retry on connect timeout?

I was having a problem where HttpURLConnection.getOutputStream() took 2-3 seconds. I set the connect timeout using HttpURLConnection.setConnectTimeout, expecting a SocketTimeoutException (wrapped by IOException) to be thrown from getOutputStream(), so I could retry the whole operation on another server.

Instead, it just works now. Does getOutputStream() try to connect internally if it gets a SocketTimeoutException?

A: 

Isn't this addressed here?

No, I don't think so.

"Some non-standard implmentation of this method may ignore the specified timeout. To see the connect timeout set, please call getConnectTimeout()."

+1  A: 

If you setConnectTimeout(), it will not retry. Otherwise, it tries just one more time before it throws IOException.

In my opinion, you should handle retry yourself though.

Do you have a reference for this?

No. We found out this behavior while looking at some HTTP traces and confirmed by looking at Java 5 source code. So this is only a special behavior of Java 5's URL handler.

The thing is ... I found that setting the timeout did seem to cause internal retries. I'm downloading the code now.
