如何用C语言开发一个通用web服务器?

用C语言开发WEB，可以用C++BUILDER6，称ISAPI，一般人可能做不起来，有点麻烦；

唯一是速度很快，别人看不到源码，掌握了编程套路，也可以开发应用；

缺点：

1。不是解释性语言，做的WEB调试非常麻烦；现在做WEB开发的，用C#、JAVA较多；都是解释性的语言；

2。因为是.DLL的二进制代码，一般商业网站不给予运行的环境，因为网站服务器会被你可能搞瘫，安全性得不到保障；所以，你得自备网页服务器；

3。得不到技术支持，因为没几个人会这种开发；

去看一下《Advanced Linux Programming》这本书吧，第11章讲的就是怎么用C语言实现一Http服务器。 这里有下载地址（英文的）： http://www.advancedlinuxprogramming.com/alp-folder 英文看起来不顺的话可以上网找找有没有中文版的这本书，应该叫Linux高级编程吧～～～参考资料： http://www.advancedlinuxprogramming.com/alp-folder
