以下代码为什么不能将 driver1的cookie加载到driver2里呢？如果我将代码换成谷歌浏览器对象，其他部分一样的代码可以成功，为什么ie浏览器就不行呢？而且driver1和driver2是在一个域名下的。

# 获取登陆后的Cookie组成的列表
cookie = driver1.get_cookies()
print(cookie)
# 关闭浏览器
driver1.close()
# 实例化第2个浏览器对象
driver2 = webdriver.Ie(iedriver)
# 添加目标页面链接
driver2.get('http://10.158.3.30/gwcl/oagwcl.aspx')
for c in cookie:
driver2.add_cookie(c)
driver2.get('http://10.158.3.30/gwcl/oagwcl.aspx')
time.sleep(10)
