jQuery的AJAX请求失败，503错误只与QUOT; HTTP：//example.com"作为价值 [英] jQuery AJAX request fails with 503 error only with "http://example.com" as value

问题描述

我有奇怪的问题。这是我的javascript：

I have the strangest problem. This is my javascript:

var value = "some_value";
$.ajax({
  url: "process.php",
  type: "POST",
  dataType: "json",
  data: {
    value: value
  },
  success: function(data) {
    console.log(data);
  }
});

没有惊喜。这是我的process.php：

No surprises here. This is my process.php:

<?php exit; ?>

其实这并不重要，什么是 process.php 里面。 该请求是成功的，每次，除非值是一个有效的URL。随着

Actually it does not matter, what is inside the process.php. The request is successful everytime, except when value is a valid URL. With

var value = "http://example.com"

在开始请求时，按照错误503服务暂时不可用失败。 什么是错我的服务器配置？我不知道什么尝试。 我没有任何的.htaccess。浏览器：Firefox的29

at the beginning the request will fail with error 503 Service temporarily unavailable. What is wrong with my server configuration? I don't know what to try. I have no .htaccess. Browser: Firefox 29.

推荐答案

这是几乎可以肯定，一个网应用防火墙。检查服务器是否正在运行 的mod_security 。您将需要查看使用的mod_security 或任何其他的服务器上运行的规则，以找到一个被阻止的URL。

This is almost certainly a web application firewall. Check whether your server is running mod_security. You will need to review the rules used by mod_security or whatever else is running on the server to find the one that is blocking URLs.
