一直以来，Web服务器识别都是使用httprint来进行扫描，现在多了一个选择了，而且还是开源的，先试试。

The httprecon project is doing some research in the field of web server fingerprinting, also known as http fingerprinting. The goal is the highly accurate identification of given httpd implementations. This is very important within professional vulnerability analysis.
Besides the discussion of different approaches and the documentation of gathered results also an implementation for automated analysis is provided. This software shall improve the easyness and efficiency of this kind of enumeration. Traditional approaches as like banner-grabbing, status code enumeration and header ordering analysis are used. However, many other analysis techniques were introduced to increase the possibilities of accurate web server fingerprinting. Some of them were already discussed in the book Die Kunst des Penetration Testing (Chapter 9.3, HTTP-Fingerprinting, pp. 530-550).
