响应中的Apache HttpClient标头问题

Question

我使用Apache HttpClient和java.sun.net.httpserver作为Server.服务器处理Http-Get请求.首先,服务器使用set-cookie标头设置会话cookie,这是由apache httpclient接受的(根据日志),但问题是cookie永远不会存储,也不会被客户端发送回服务器.我已经使用一些Web浏览器测试了服务器应用程序,并且一切正常.因此问题似乎是在客户端,特别是考虑到所有cookie都被接受与log4j一起登录.

Answer 1

Set-cookie: SESSID=0.9499481656989606; expires=Tue, 19-4-11 18:28:43 GMT; Max-Age=3600; Path=/; Version="1"

Cookie值有多个问题:

(1)它通过使用带逗号的属性值而不用引号括起来违反了RFC 2109和RFC 2965规范.

(2)到期属性看起来很可疑.我怀疑失效日期设置不正确,而cookie只是在接受的同一时刻到期.此外,版本1 cookie(符合RFC 2109/RFC 2965)甚至不应该首先使用它.

cookie也有Max-Age新的cookie应该使用的属性,但由于cookie格式不正确,HttpClient将cookie视为旧的Netscape样式,并且该Expiry属性优先于Max-Age
