6.Quick start
Here to show you how to quickly create a rule and complete the modification of the http request or response
Take https://www.fiddler2.com/UpdateCheck.aspx?isBeta=False as an example (the request is actually a request for a fillder update check)
Suppose we want to change the value of isBeta in the url to true and change the Connection: header to Keep-Alive.
You only need to fill in the information shown above, click on the bottom right corner to confirm
Set the rule matching as shown above and check the rules you need to participate in the match (the request with the sequence number 6 in the figure is the rule we just created)
When the system matches the http request, the matching session in the left side of the fiddler session list, and the right rule list are matched. The rule is highlighted in light yellow (the highlight of the rule list will be 2-3 seconds). After disappearing, the corresponding log will appear in the log log area.
Tampering results as shown in the Inspectors red mark above, you can see that the modification of http has taken effect
