Fiddler 2 擦除我的 Internet Explorer 代理设置
我刚刚开始使用 Fiddler 2 为我一直在创建的基于 REST、JSON 和 SOAP 的服务创建请求对象。 到目前为止效果很好。
当我尝试通过 Internet Explorer 使用公司的一些资源时，问题就出现了。 我遇到了某种 DNS 错误，我意识到这是因为每次打开 fiddler（IE6 和 IE8）时我的代理设置都会被擦除。 有谁知道 Fiddler 可能在这里“摆弄”什么会导致这样一个奇怪的问题。
更多信息：这种情况发生在运行 Windows XP 的 Virtual PC VM 上。 被清空的确切内容位于“工具”->“Internet 选项”->“连接”->“LAN 设置”窗口中。 两个复选框均已选中，并且“高级”窗口中的字段已填充。 随后，全场一片空白。
I just started using Fiddler 2 to create request objects for REST,JSON, and SOAP based services that I have been creating. It has worked great so far.
The problem came when I attempted to use some of my company resources through Internet Explorer. I was getting some sort of a DNS error, which I realized was happening because my proxy settings were getting wiped every time I open fiddler (IE6 and IE8). Does anyone know what Fiddler might be "fiddling" with here that would cause such a strange problem.
More info: This is happening on an Virtual PC VM running Windows XP. The exact stuff that is being blanked resides in the Tools->Internet Options->Connections->LAN Settings window. Both checkboxes there were checked and the fields in the Advanced window were populated. Afterwards, all were blanked.

确保您的代理没有指向 .PAC 文件。 Fiddler 在启动时不会“保留”此配置。 相反，请手动键入实际的代理 FQDN。
Make sure your proxy is not pointing to a .PAC file. Fiddler does not "keep" this configuration when launched. Instead, type the actual proxy FQDN manually.
Fiddler 终止了我的 ie 连接，但 firefox 连接仍然存在......
我遇到了错误“Fiddler：www.google.com.au 的 DNS 查找失败。没有这样的主机已知”
我刚刚修复了我的错误。 我将“http://localhost:8888/VirtFolder/MyWebApp”放入 url 中，它似乎使连接和 IE 再次开始工作。
Fiddler killed my ie connection but firefox connection remained....
I had an error "Fiddler: DNS Lookup for wwww.google.com.au failed. No such host is known"
I just fixed mine. I put "http://localhost:8888/VirtFolder/MyWebApp" into the url and it seemed to make the connection and IE start to work again.
它被清空了，因为 Fiddler 通过将自身添加为代理而不是使用当前的代理设置来工作。 这就是它拦截所有流量的方式。
好消息是，只需进行一些配置，您就可以将 Fiddler 配置为代理并使用手动配置的公司代理：
Fiddler Web 调试器 - 配置客户端
It's getting blanked out because Fiddler works by adding itself as a proxy instead of using your current proxy settings. That's how it intercepts all the traffic.
The good news is that, with a little configuration, you can configure Fiddler to act as a proxy AND use your manually configured corporate proxy as well:
Fiddler Web Debugger - Configuring Clients
1.) 使用管理员权限打开命令提示符
2.) 键入 NETSTAT -AB
3.) 查看端口 8888 上是否已在运行任何内容
如果是，那就是您的问题。 将 Fiddler 更改为在端口 8889（或下一个可用端口）上运行
1.) 工具 -> Fiddler 选项 -> 连接-> Fiddler 监听端口 -> 8889
1.) Open a command prompt with Administrator priveleges
2.) Type NETSTAT -AB
3.) See if anything is running on Port 8888 already
If so, that is your problem. Change Fiddler to run off port 8889 (or next available port)
1.) Tools -> Fiddler Options -> Connections -> Fiddler listens on port -> 8889
Fiddler 在启动时更改您的代理设置，并在 Fiddler 关闭时将其恢复到启动之前的状态。
然而，这并不能真正解释你的问题，因为当 Fiddler 运行时，它会使用你的旧代理服务器作为上游代理，当你关闭它时，它会将设置恢复到之前的状态。
如果您不想在 IE 中使用 Fiddler，请取消选中“工具”/“Fiddler 选项”中的“充当系统代理”复选框； 请注意，您需要手动配置应用程序或框架（例如.NET）以使用 127.0.0.1:8888 作为代理。
Fiddler changes your proxy settings on startup and reverts them back to what they were before you started when Fiddler is closed.
However, that doesn't really explain your problem, because when Fiddler is running it will use your old proxy server as an upstream proxy, and when you shut it down, it reverts the settings back to what they were before.
If you don't want to use Fiddler with IE, uncheck the "Act as system proxy" checkbox inside Tools / Fiddler Options; note that you'll need to manually configure your application or framework (e.g. .NET) to use 127.0.0.1:8888 as a proxy though.
