With Apache HttpClient, why isn't my connection timeout working?

My implementation of httpclient occasionally throws an exception when calling doGetConnection(). However, I have the following timeout set

_moHttpClient.setHttpConnectionFactoryTimeout(30000);

it looks almost like my timeout is not being picked up. Is there anywhere else I need to set a timeout to ensure this behaviour does not re-occur

What exception are you getting thrown ?

Don't forget you have two timeouts to change/check. From HttpConnectionParams

setConnectionTimeout()
setSoTimeout()

so you can control how long you wait for a connection to the server, and how long operations on the socket can take before timing out.

    HttpConnectionManagerParams cmparams = new HttpConnectionManagerParams();
    cmparams.setSoTimeout(10000);
    cmparams.setTcpNoDelay(true);
    HttpConnectionManager manager = new SimpleHttpConnectionManager();
    manager.setParams(cmparams);
    params = new HttpClientParams();
    params.setSoTimeout(5000);
    client = new HttpClient(params, manager);

I wonder why I have two different SoTimeouts set. Maybe I was trying to find out which one was actually active, as I had the same problems as you when I used it.

The above is in live code at our place right now, but I cannot say whether it works because it's correct, or because providence is smiling down on me (and the other end is usually always available).

cmparams.setSoTimeout(10000);

This one is for all HttpClient by default.

params.setSoTimeout(5000);

And this one is for a particular httpclient.
