Fiddler tool filter Features
FIG is a filter function interface
1.Actions: meaning is the meaning of the action, that is, what to do operations inside contains several options:
Run Filterset now: filtering is performed immediately
Load Filterset: load a local file filter settings
Save Filterset: Saved filters to file
2 , in order to modify the filter criteria below whether to use a filter, select this option only after the bottom of the filter conditions independently of each other, they can also be combined with each other: Use Filters.
3、Hosts：
Filtered by host name.
No Zone Filter: no filtering through space, this is a fair share of network with external networks
show only Intranet Hosts: 内网
show only internet Hosts：外网
No Host Filter: no filtering by hostname
Hide the following Hosts: host name hidden below the input request
show only the following Hosts: a request to display the host name entered below
flag the following Hosts: sign request host name below to enter over;
For example, FIG input www.baidu.com
Blue color is filtered out of the bag
4、Client Process
To filter according to the client process, check the show only traffic from, then you can choose which process to come to a session
5、Request Headers：
Show only if URL contains 和 Hide if URL contains 使用方法类似功能相反。都是url中包含某些字符过滤，多种情况空格分隔。Hide if URL contains 可以简单理解为隐藏所有js请求，如下例子Show only if URL contains，是展示所有js请求：
6、Breakpoints：
（断点添加可以在工具栏中Rules中进行设置）
断点调试的步骤：
（1）当我们在这个里边设置了断点过滤，那么就会在相应的会话请求中插入断点。
例如下边我在get 请求中插入断点。那么可以发现在执行get 请求的会话是红色的图标。
这个时候如果你要对其中某一条进行断点调试的话，那么就双击，然后就会显示这样一个界面：
点击Break on Response 以后，你切换到下边的TextView选项卡里边，可以发现返回的数据，然后就可以进行修改了
7、Response Status Code：
响应码过滤，就是隐藏相应状态码的请求
过滤后如图：
8、Response Type and Size：
这部分是根据响应类型和大小的过滤：
Block script files：阻止脚本文件，显示为404；
Block image files：阻止图片文件；
Block SWF files：阻止SWF文件；
Block CSS files：阻止CSS文件；
Block的过滤是挺有意思，如果你选中了block css那么浏览器就加载不到css了。
结果如下图：
9、Response Headers：
是对response header的标志和修改。
Flag response that set cookies：标记会设置cookie的响应；
Flag response with headers：标记带有特定header的响应；
Delete response headers：删除响应header；
Set response header：设置响应的header；
