Vikram,
I hope what is to follow will clarify things a little
(1)
===================================================================
HostConfiguration host = new HostConfiguration();
host.setHost("www.google.com");
===================================================================
These are the defaults that apply only when some host parameters have
not been explicitly defined by the method itself. Thus, they are not
supposed to mutate as a result of method execution
Consider the following:
===================================================================
HttpClient client = new HttpClient();
HostConfiguration hostconfig = new HostConfiguration();
hostconfig.setHost("www.mycompnany.com");
HttpMethod httpget = new GetMethod("http://www.anothercompnany.com/";);
client.executeMethod(hostconfig, httpget);
===================================================================
I assume you'd still want this method to be executed against
http://www.anothercompnany.com/ not http://www.mycompnany.com/, right?
So, if you want to know the exact host parameters applied during the
method execution, you should call
===================================================================
method.getHostConfguration().getParams().getParameter("http.useragent"));
===================================================================
Please let me know if that sounds reasonable/unreasonable
(2)
All this said, I have to admit that current host configuration related
code is a horrible mess. I will provide a refactoring patch shortly
Hope this helps
Oleg
