[HttpClient] Re: How to clear cookies before connect server with httpclient 3.0-dev?

[Michael Becke <be...@u.washington.edu>]

Hi Dongsheng,

In your sample you are creating a new instance of HttpState when 
executing the method.  Since new instances have no cookies there are 
none to remove.  You can also disable cookies by using the ignore 
cookies policy:

method.getParams().setCookiePolicy(CookiePolicy.IGNORE_COOKIES)

Removing all cookies can also be done by calling purge with the date 
parameter:

client.getState().purgeCookies(new Date(Long.MAX_VALUE));

Even though there are these options there should also be a method on 
HttpState that removes all cookies.  I will add an enhancement request 
for this.
