Subject Re: Problem with Preferences Architecture
Date Wed, 29 Sep 2004 12:29:40 GMT


I hope what is to follow will clarify things a little

HostConfiguration host = new HostConfiguration();

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();

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



Please let me know if that sounds reasonable/unreasonable

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
