大多数Web浏览器中都可以使用PUT，DELETE，HEAD等方法吗？

问题：

I've seen a couple questions around here like How to debug RESTful services , which mentions: 我在这里看到了几个问题，例如如何调试RESTful服务，其中提到：

Unfortunately that same browser won't allow me to test HTTP PUT, DELETE, and to a certain degree even HTTP POST. 不幸的是，同一浏览器不允许我测试HTTP PUT，DELETE，并且在某种程度上甚至无法测试HTTP POST。

I've also heard that browsers support only GET and POST, from some other sources like: 我还听说其他一些来源的浏览器仅支持GET和POST：

However, a few quick tests in Firefox show that sending PUT and DELETE requests works as expected -- the XMLHttpRequest completes successfully, and the request shows up in the server logs with the right method. 但是，在Firefox中进行的一些快速测试表明，发送PUT和DELETE请求可以按预期方式工作XMLHttpRequest成功完成，并且该请求以正确的方法显示在服务器日志中。 Is there some aspect to this I'm missing, such as cross-browser compatibility or non-obvious limitations? 我是否缺少某些方面的信息，例如跨浏览器兼容性或非显而易见的限制？
