我正试图使用PHP和cURL发布到一个网站，并获得一个搜索结果，作为概念验证的一部分。但我的反应与我直接访问网站时得到的反应不同。我已经使用FireBug捕获了所有的post参数和头文件，并使用cURL发送了所有这些参数和头，但响应仍然不一样。有人能帮我弄清楚我做错了什么吗？
我尝试访问的网站是：http://book.goindigo.in/skylights/cgi-bin/skylights.cgi
在该网站上，我正在进行单向搜索，将返回一系列航班（例如，9月25日的孟买-德里）。我并不担心这个结果。显示航班后，如果选择了特定航班，则会在左侧的"价格汇总"部分下显示票价明细。为了得到这个价格摘要，他们启动了一个ajax调用，这就是我想要使用PHP和cURL模拟的。
当通过站点访问时，ajax调用返回一组javascript变量作为响应。但是，当通过cURL访问时，相同的调用返回页面的完整html，而不是预期的javascript变量。
如有任何帮助，我们将不胜感激。
感谢
