HTTP/1.0 - 417 Expectation failed

[Juanjo]

Hi,
 
    I am receiving this header from a server
 
    HTTP/1.0   - 417 Expectation failed
 
    How can I solve this from my client?
 
    How can I remove header Expect: 100-Continue?
 
    I used:
 
    HttpParams params = new BasicHttpParams();
    params.setParameter ("http.protocol.handle-redirects",false);
 
    but it doesn't work.
 
 
Thanks in advance
