Thank you for your reply .. but I have another question

When I run sample code in the bottom of
http://jakarta.apache.org/commons/httpclient/sslguide.html page
(accessing https://www.verisign.com), I get Exception msg like this :

------------------------------------------------------------------------

but when I altered the destination (field TARGET_HTTPS_SERVER) became
www.verizon.com and www.mail.yahoo.com the program doing fine.

But then when change again the destination into sourceforge.net, the
Exception as above happen again.

www.verisign.com and sourceforge.net have the same characteristic that
is when I browse them with Microsoft Internet Explorer 6, they yield a
dialog frame that say "this page contain both secure and nonsecure items
.... "

Is the characteristic above that caused me unable to open
www.verisign.com and sourceforge.net? Or can you think another causes?
And please tell how do I deal with it?

Thank you ...

Please check out the SSL guide

http://jakarta.apache.org/commons/httpclient/sslguide.html

which should answer your questions.

As statet frequently on this list, HttpClient makes no assumptions about

the underlying SSL implementation. Please refer to the documentation of 
your SSL implementation for further information.
