为什么 http 请求挂在我的 python 脚本中？
我的一个脚本在 XP 系统上完美运行，但确切的脚本在 2003 系统上挂起。我总是使用 mechanize 发送 http 请求，这里有一个例子：
import socket, mechanize, urllib, urllib2
socket.setdefaulttimeout(60) #### No idea why it's not working
MechBrowser = mechanize.Browser()
Header = {'User-Agent': 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.8) Gecko/20100722 Firefox/3.6.8 GTB7.1 (.NET CLR 3.5.30729)', 'Referer': 'http://www.porn-w.org/ucp.php?mode=login'}
Request = urllib2.Request("http://google.com", None, Header)
Response = MechBrowser.open(Request)
我不认为我的代码有什么问题，但是每次当涉及到对特定 url 的某个 http POST 请求时，它都会挂在那台 2003 年的计算机上（仅在该网址上）。这一切的原因可能是什么？我应该如何调试？
顺便说一句，该脚本直到几个小时前都运行良好。并且没有更改任何设置。
One of my script runs perfectly on an XP system, but the exact script hangs on a 2003 system. I always use mechanize to send the http request, here's an example:
import socket, mechanize, urllib, urllib2
socket.setdefaulttimeout(60) #### No idea why it's not working
MechBrowser = mechanize.Browser()
Header = {'User-Agent': 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.8) Gecko/20100722 Firefox/3.6.8 GTB7.1 (.NET CLR 3.5.30729)', 'Referer': 'http://www.porn-w.org/ucp.php?mode=login'}
Request = urllib2.Request("http://google.com", None, Header)
Response = MechBrowser.open(Request)
I don't think there's anything wrong with my code, but each time when it comes to a certain http POST request to a specific url, it hangs on that 2003 computer (only on that url). What could be the reason of all this and how should I debug?
By the way, the script runs all right until several hours ago. And no setting is changed.

您可以使用 Fiddler 或 Wire Shark 查看 HTTP 级别发生的情况。
还值得检查该计算机是否已被阻止向您尝试访问的计算机发出请求。使用常规浏览器（带有您自己的 HTML 表单）和 Mechanize 使用的 HTTP 库，看看是否可以手动构造请求。 Fiddler 也可以帮助你做到这一点。
You could use Fiddler or Wire Shark to see what is happening at the HTTP-level.
It is also worth checking out if the machine has been blocked from making requests to the machine you are trying to access. Use a regular browser (with your own HTML form), and the HTTP library used by Mechanize and see if you can manually construct a request. Fiddler can also help you do this.
