I don't know what is Web Server 1.0, it is in the response that it isn`t in
my hands.

How can I do to disable 'expect-continue'?

It work properly on Windows but not on Linux.
I think that the server is a websphere.

Hi Oleg, thanks for your answer.

These are the diferences
Number 2 under windows is running fine. The code is the same in boths environment but in the log, there is a diference in the order that postparams are sent. 

¿any ideas?

Thanks



For the love of Jesus, what on earth is Web Server 1.0? Whatever that piece
of software is, it appears to have issues with 'expect-continue'
handshaking. Interestingly enough, 'expect-continue' appears to work
properly on Linux and to fail on Windows. So, try disabling
'expect-continue' and see if that makes any difference.

Use context / wire logging to examine the HTTP session and find out why your application behaves differently in different environments.

Hi,
In windows using tomcat 6.0 and jdk 1.6, my program runs properly. It connect to a website by post, sending parameters, that return a 302. Then, It reads the Location head an makes a Get call. When I deploy this program in linux with tomcat 5, the location head returns the home url, not the right one. This is the code: HttpClient client = new DefaultHttpClient(); 
    HttpPost req = new HttpPost(http://www.theweb.com);
    List<NameValuePair> formparams = new ArrayList<NameValuePair>();
    formparams.add(new BasicNameValuePair("aaa","sss"));
    ...
    UrlEncodedFormEntity param = new UrlEncodedFormEntity(formparams);
    req.setEntity(param)
    HttpResponse res = client.execute(req)
    entity =res.getEntity();
    Header loc = res.getFirstHeader("Location");
.... Another program that do the same but no redirection and using BasicResponseHandler runs properly in both systems. 
Please help,
Tanks Juanjo
