In your Servlet code, use the "setMaxInactiveInterval(int seconds)" method of the "HttpSession" class to set the Session Timeout Value for your server. The Servlet API says : public void setMaxInactiveInterval(int interval) Specifies the time, in seconds, between client requests before the servlet container will invalidate this session. A negative time indicates the session should never timeout. Parameters: interval - An integer ... |
Wouldn't that be nice? You might get away with it in a single-threaded client. But if you're in a multi-threaded environment you'd have to track threads coming in and out of the method that need the lower value. See the Apache Commons HttpClient package. It has a class compatible with HttpURLConnection that includes timeout. I tried to find solutions for this ... |

Are you sure that the server side C code is working fine? I believe you are getting timed out while writing to server. Possibly your can use a network analyzer to see, whats going down the wire. Additionally, why are you calling setSOtimeout twice. Calling it just before read is good enough. |
