此处同时支持解析那些“非正常”的Set-Cookie：


MSPRequ=/;Version=1;version&lt=1328770452&id=250915&co=1; path=/;version=1,MSPVis=$9; Version=1;version=1$250915;domain=login.live.com;path=/,MSPSoftVis=@72198325083833620@:@; domain=login.live.com;path=/;version=1,MSPBack=1328770312; domain=login.live.com;path=/;version=1

例 7.10. parseSetCookie 的使用范例


    resp = (HttpWebResponse)req.GetResponse();
    //update latest cookies
    gCurDomain = commLib.extractDomain(getItemsUrl);
    CookieCollection parsedCookies = commLib.parseSetCookie(resp.Headers["Set-Cookie"], gCurDomain);
    commLib.updateLocalCookies(parsedCookies, ref skydriveCookies);

另外一个例子：


    resp = (HttpWebResponse)req.GetResponse();
    // here resp.Cookies may be uncorrect, so parse the returned Set-Cookie to get real cookies
    parsedCookies = commLib.parseSetCookie(resp.Headers["Set-Cookie"], gCurDomain);
    commLib.updateLocalCookies(parsedCookies, ref skydriveCookies);

【已解决】又发现一个C#中解析Set-Cookie的一个bug：无故地添加cookie的path域中的例子：


    HttpWebResponse addNk1Response = crl.getUrlResponse(addNk1Url, headerDict: headerDict, postDict: postDict);//<script>location.href='/add/'</script>
    String curDomain = crl.extractHost(addPhpUrl);//new.guguyu.com
    CookieCollection parsedCookies = crl.parseSetCookie(addNk1Response.Headers["Set-Cookie"], curDomain);
    CookieCollection curCookies = crl.getCurCookies();
    crl.updateLocalCookies(parsedCookies, ref curCookies);
    crl.setCurCookies(curCookies);

为了更加方便使用，又添加了一个重载函数：


    // parse Set-Cookie string part into cookies
    // leave current domain to empty, means omit the parsed cookie, which is not set its domain value
    public CookieCollection parseSetCookie(string setCookieStr)
    {
        return parseSetCookie(setCookieStr, "");
    }

所以上述调用此函数时，也可以不指定对应的domain：


    resp = (HttpWebResponse)req.GetResponse();
    //update latest cookies
    CookieCollection parsedCookies = commLib.parseSetCookie(resp.Headers["Set-Cookie"]);
    commLib.updateLocalCookies(parsedCookies, ref skydriveCookies);

当然，此时要注意，domain为空的cookie，一般来说，在后续的http的请求中，往往都是由于domain不匹配，而变成无效的cookie。

所以此处你需要知道自己在干什么，搞清楚了，再去使用此不指定domain的版本的parseSetCookie。
