Fiddler-Grab Bag Tool

Fiddler is a Web debugging agent. It can record HTTP requests between all clients and servers, allow you to monitor, set breakpoints, and even modify input and output data, Fiddler contains a powerful event-based scripting subsystem, and is able to use the. NET Framework language extension. Edit this paragraph Microsoft fiddler  Microsoft's Fiddler contains a simple yet powerful JScript. NET Event Scripting subsystem that is very flexible and great to support numerous HTTP debugging tasks. Fiddler is written in C #. It is also an HTTP debugging agent, it can record all of your computer and the Internet between the HTTP communication, Fiddler can also let you check all the HTTP communication, set breakpoints, and fiddle all the "in and out" of the data (referring to Cookie,html,js, CSS and other files, which can make you arbitrarily modify the meaning). Fiddler is simpler than other network debuggers because it exposes only HTTP traffic and provides a user-friendly format. Edit this section of Microsoft's Fiddler using  fiddler support breakpoint Debugging concepts, when you select Beforerequest in the Software menu-rules-automatic breakpoints Options, Or when these request or response properties match the target's criteria, fiddler can pause HTTP traffic, allowing the request and response to be modified. This functionality is useful for security testing and can also be used for general functional testing, as all code paths can be used for drills.  users can join a Inspector plug-in object to write Fiddler extensions using any language under. Net. Requestinspectors and Responseinspectors provide a format specification, or a specified (user-defined) HTTP request and Response view.  by displaying all of the HTTP traffic, fiddler can easily demonstrate what is used to generate a page, through the statistics page (that is, the large box on the left of fiddler) users can easily use multiple selection, to get a Web page "Total weight" (page file and related JS, CSS, etc.) you can also easily see a page you have requested, how many times it has been requested, and how many bytes have been converted. In  addition, by exposing the HTTP header, users can see which pages are allowed to be cached on the client or proxy side. If a response does not contain a Cache-control header, then he will not be cached on the client.
