Of course, I do not mind. However, the preferred way of addressing
HttpClient developers is through the HttpClient mailing list. 


By participating at the mailing list you can benefit from hearing
diverse opinions of all those involved in HttpClinet project. Besides,
there are people whose contribution to the HttpClient project far
exceeds mine. They may be in a by far better position to answer your

That has been a conscious decision on the part of HttpClient developers.
Client-side cookies are different logical entities compared to
server-side cookies. Server-side cookies represent 'Set-Cookie' response
headers, whereas client-side cookies represent 'Cookie' request headers.
Besides, it doubt that tightly coupling HttpClient with
javax.servlet.http package would be such a great idea. However, I have
to assume that under your specific circumstances such design decision
may be justifiable.

This is as true as it is said. Clearly Cookie needs to be an interface.
I have been planning to introduce a new Cookie interface as I get down
to working on RFC 2965 support (Cookie2 spec). This refactoring has to
done after 2.0 release, though, as it would break API compatibility. 

Feel free to file a bug report to make sure that this suggestion does
not go forgotten


Should you ever embark on such an undertaking as writing your own cookie
implementation, be warned, though, that you would also need to provide a
custom implementation of the CookieSpec interface capable of dealing
with your custom cookies.
