关于HttpOnly对于防范XSS来获取 cookies信息的分析,请参考剑心同学写的:利用httponly提升应用程序安全性,这里仅把常用的一些Web开发语言的设置方法整理总结下,备用。
javaEE中的设置:
API中没有提供具体的操作方法或者函数属性来设置,不知道后续版本是否会提供,下面为变通设置方法:
————————————————————————————–
response.setHeader(”Set-Cookie”, “cookiename=value;
Path=/;Domain=neeao.com;Max-Age=seconds;HTTPOnly”);
————————————————————————————–
ASP.NET中的设置
.net2.0以上版本支持在Web.config文件中来配置全局的httponly,设置如下,在web.config中添加一个节点即可:
------------------------------------------------------------------
<httpCookies httpOnlyCookies="true" />
------------------------------------------------------------------
.net2.0以上版本cookie对象中,直接有一个HttpOnly的参数供调用,使用方法如下:
C#代码:
------------------------------------------------------------------
HttpCookie myCookie = new HttpCookie("myCookie");
myCookie.HttpOnly = true;
Response.AppendCookie(myCookie);
-------------------------------------------------------------------
vb.net代码
-------------------------------------------------------------------
Dim myCookie As HttpCookie = new HttpCookie("myCookie")
myCookie.HttpOnly = True
Response.AppendCookie(myCookie)
-------------------------------------------------------------------
在asp.net1.1中也可以设置全局的cookies HttpOnly,在全局文件Global.asax的application节点的 Application_EndRequest事件中添加:
-------------------------------------------------------------------
protected void Application_EndRequest(Object sender, EventArgs e)
{
string authCookie = FormsAuthentication.FormsCookieName;
foreach (string sCookie in Response.Cookies)
{
if (sCookie.Equals(authCookie))
{
Response.Cookies[sCookie].Path += ";HttpOnly";
}
}
}
-------------------------------------------------------------------
在代码中写的话,就需要这样来添加了:
--------------------------------------------
Response.Cookies[cookie].Path += ";HTTPOnly";
---------------------------------------------
PHP中的设置
PHP5.2以上版本已支持HttpOnly参数的设置,同样也支持全局的HttpOnly的设置,在php.ini中
-----------------------------------------------------
session.cookie_httponly =
-----------------------------------------------------
设置其值为1或者TRUE,来开启全局的Cookie的HttpOnly属性,当然也支持在代码中来开启:
-----------------------------------------------------
<?php
ini_set("session.cookie_httponly", 1);
// or
session_set_cookie_params(0, NULL, NULL, NULL, TRUE);
?>
-----------------------------------------------------
Cookie操作函数setcookie函数和setrawcookie函数也专门添加了第7个参数来做为HttpOnly的选项,开启方法为:
-------------------------------------------------------
setcookie("abc", "test", NULL, NULL, NULL, NULL, TRUE);
setrawcookie("abc", "test", NULL, NULL, NULL, NULL, TRUE);
-------------------------------------------------------
对于PHP5.1以前版本以及PHP4版本的话,则需要通过header函数来变通下了:
-------------------------------------------------------------
<?php
header("Set-Cookie: hidden=value; httpOnly");
?>
-------------------------------------------------------------
Asp中的设置
asp的内置对象中没有提供相关方法,只能变通来实现了:
-----------------------------------------------------<%
