python http状态码

我正在用python编写自己的目录破坏器，并在安全可靠的环境中针对我的Web服务器对其进行测试.该脚本基本上试图从给定的网站检索公用目录，并查看响应的HTTP状态代码，从而能够确定页面是否可访问.
首先，脚本将读取包含所有要查找的有趣目录的文件，然后以以下方式发出请求:

I'm writing my own directory buster in python, and I'm testing it against a web server of mine in a safe and secure environment. This script basically tries to retrieve common directories from a given website and, looking at the HTTP status code of the response, it is able to determine if a page is accessible or not.
As a start, the script reads a file containing all the interesting directories to be looked up, and then requests are made, in the following way:

for dir in fileinput.input('utils/Directories_Common.wordlist'):

    try:
        conn = httplib.HTTPConnection(url)
        conn.request("GET", "/"+str(dir))
        toturl = 'http://'+url+'/'+str(dir)[:-1]
        print '    Trying to get: '+toturl
        r1 = conn.getresponse()
        response = r1.read()
        print '   ',r1.status, r1.reason
        conn.close()

然后，解析响应，如果返回的状态码等于"200"，则可以访问该页面.我已经通过以下方式实现了所有这些:

Then, the response is parsed and if a status code equal to "200" is returned, then the page is accessible. I've implemented all this in the following way:

if(r1.status == 200):
    print '\n[!] Got it! The subdirectory '+str(dir)+' could be interesting..\n\n\n'

对我来说，一切似乎都很好，除了脚本将其标记为实际上不是可访问的页面.实际上，该算法仅收集返回"200 OK"的页面，但是当我手动浏览这些页面时，我发现它们已被永久移动或访问受限.出了点问题，但我无法确定应该在哪里正确修复代码，我们将为您提供任何帮助.

All seems fine to me except that the script marks as accessible pages that actually aren't. In fact, the algorithm collects the only pages that return a "200 OK", but when I manually surf to check those pages I found out they have been moved permanently or they have a restricted access. Something went wrong but I cannot spot where should I fix the code exactly, any help is appreciated..
