Connection Reset error in HttpClient

Question

This is scenario I am testing. The steps are as follows

Create an instance of HttpClient(org.apache.commons.httpclient.HttpClient)3.1
Use the instance to get response from a url (http://www.example.com/submitData)
Bring down the server hosting the url mentioned in step 2.
Bring up the url
Wait till the url is up
Use the instance of HttpClient created in step 1 to get response from the url (http://www.example.com/getData)

I get an error - Connection Reset. Can anyone help me understand.

I have used the following params in the HttpClient

    httpClient.getParams().setParameter("http.socket.timeout", new Integer(0));
    httpClient.getParams().setParameter("http.connection.stalecheck", new Boolean(true));

Edited after comments from Peter This is how I create the HttpClient

HttpClient httpClient = new HttpClient();
AuthScope authScope = new AuthScope("www.example.com", 80, AuthScope.ANY_REALM);
Credentials defaultcreds = new UsernamePasswordCredentials("username", "pwd");
httpClient.getState().setCredentials(authScope, defaultcreds);
httpClient.getParams().setParameter("http.socket.timeout", new Integer(0));
httpClient.getParams().setParameter("http.connection.stalecheck", new Boolean(true));

To establish connection, I use the following

GetMethod getMethod = new GetMethod("http://"+httpClient.getHostConfiguration().getHost()+"/getData");
int statusCode = httpClient.executeMethod(getMethod);

I want the httpclient instance to preserve the hostname and port and credentials.

This is exact execption message that I get - "Connection reset".

More info - I am executing the test from eclipse. If I run the test case in debug mode, I dont get this exception.

I think the behaviour is reasonable because when the server goes down the client socket on the server goes away too. The client still holds old socket but this socket is gone on the server. You should reconnect from client.

AFAIK the stale parameter allows the client to close the connection the clean way (without Exception) but not prevent from disconnection.

But I am not looking to persist any connection with the url. The calls made by HttpClient are REST calls and all I want is the HttpClient object to preserve data like host and port. – BKSingh Mar 27 '14 at 10:50
So show us how do you instantiate HttpClient and opens the connection. – PeterMmm Mar 27 '14 at 11:00
I have modified the question to reflect the steps involved in creating the instance of HttpClient – BKSingh Mar 28 '14 at 06:29
Can you post the exact Exception message. – PeterMmm Mar 28 '14 at 07:36
@PeterMnn I have edited the question to add more info. Thanks for your help. – BKSingh Mar 28 '14 at 09:15

This looks suspicious

httpClient.getParams().setParameter("http.socket.timeout", new Integer(0));

Having a timeout set to 0ms would likely terminate the request prematurely?
