Hello Frank, the problem with the Sun site is that HttpClient does not support cross host redirects. See here for directions:
http://jakarta.apache.org/commons/httpclient/redirects.html For Yahoo with it's HTTPS URL, you have to install or enable SSL support. See here for directions: http://jakarta.apache.org/commons/httpclient/sslguide.html cheers and good luck, Roland "Min (Frank) Ni" <[EMAIL PROTECTED]> 28.04.2004 16:28 Please respond to "Commons HttpClient Project" To: "Commons HttpClient Project" <[EMAIL PROTECTED]>, <[EMAIL PROTECTED]> cc: Subject: RE: Yahoo login with Httpclient Hi Oleg: Thanks for your reply.
