Question

单击链接会导致两次调用该页面到服务器。我安装livehttp并检查了标题，但无法弄清楚它为什么发送第二个请求。

http://example.com/schedule?delete=290376

Answer 1

如果您找不到解决方案：

我偶然发现了同样的问题，似乎与页面编码有关。如果FireFox下载包含无效字符的页面（例如，内容类型标题为其他内容的页面内的utf-8字符），则它将再次下载该页面并按其尝试的编码进行解析猜测它在第一页中检测到的无效字符。

因此，请确保您的页面返回正确的Content-type标头，或者包含具有正确编码的元http-equiv标头。

Answer 2

你碰巧没有使用firefox，有web开发人员工具栏，还有显示页面验证吗？

我在黑暗中猜测你的enviro，但是我的团队和我已经能够证明在firefox中安装了工具栏并且设置了页面验证实际上重复了POST和GET，因为它发送了相同的内容页面数据到验证服务。

Firefox发送两个获取网站的请求
