Dear Gentlemen, I find Jigsaw and Winie to be invaluable, thank you very much for sharing this work. I have studied all the posted resources, yet I still do not understand how to handle Client-Side cookies. Posted below is sourcecode ("CookieTest.java") and its output, that uses Client-Side Jigsaw components to send an HTTP.GET Request to www.netscape.com. As indicated by output enumeration of the Reply Header Descriptions, the Reply contains a "set-cookie" header and applying the methods: getHeaderValue("set-cookie") and value.getValue() to the Reply does indeed returns an unparsed "set-cookie" value for the netscape.com Domain (as expected). However, the CookieFilter and HttpManager do not appear to process this information because a "cookie" header does is enumerated in the Request2 headers (to the same URL: www.netscape.com). Furthermore, applying the method: getSetCookie() to the Reply returns an empty SetCookieList. So, I would be extremely grateful if you could tell me what I am doing wrong. Specifically: 1.) Why do CookieFilter and HttpManager appear not to process the "set-cookie" header in the Reply by not yielding a "cookie" header in Request2? 2.) Why does Reply.getSetCookie() generate an empty SetCookieList while getHeaderValue("set-cookie") and value.getValue() appear to find a cookie. 3.) And finally, is there any technical reason why CookieFilter has not been incorporated into Winie? (I can usually answer my own Client-Side questions by studying Winie sourcecode.)
