Is there any instruction in FiddlerScript that can rewrite URLs?

For example, when Firefox requests Fiddler to fetch 'https://www.website.com/?sid=100', Fiddler removes the 'sid=100' variable from the URL and calls 'https://www.website.com/'. Then it returns the data to Firefox as if it were retrieved from 'https://www.website.com/?sid=100'.

Thank you!

Hi!

Is it possible to configure Fiddler Everywhere to save (I only need headers) the traffic log at certain times? A script would be great too if there is no GUI option.

Thanks in advance!

Fiddler's domain specific certificate for each web site only valid for one year.  Is it possible to change domain specific certificate valid time to ten year or other times? 

If no possible , what shuould do if after the valid time?

I have tried all the methods on this website, but I am unable to intercept HTTPS. Please help me.

请尝试使用 F5 刷新页面，它会提示：对不起，您已被阻止。

谢谢。

I manually added the fiddler cert to the trust certificate folder, but fiddler is still showing a red dot next to trust root certificates.

when i click on the button to have the cert added, it fails.  I don't know what do do next.

In Fiddler Everywhere on Mac I try creating a redirect to catch requests sent to https://my.url.here/this/that/0.0.112/filename and serve some locally stored files instead. This is for a development environment on a project. I have created the following rule:

Conditions:
URL Contains: https://my.url.here/this/that/

Rules:
Update Url
Regular expression:
/https:\/\/my.url.here\/this\/that\/[0-9\.]+\/(.+)
/Users/firtname.lastname/Projects/projectname/dist/$1

The Condition is triggered because I also have a rule to color the requests and I can see that the requests are colored as I expect it. The regex Rule is probably not executed because the files are still served from https://my.url.here/this/that/... instead of the locally stored files.

Could you please advise what I am doing wrong with my regex or anything else?

Thank you.

One of my clients has Fiddler installed and running while they utilize our web application. They said that when Fiddler is running, they will run into a blank page right away. They said if they restart their computer, the blank page issue will resolve itself. They said this started happening once Fiddler was installed. Any ideas?

I am using Fiddler Classic with one of my clients and now that Fiddler has been installed and is running, they are saying performance on our application has become worse. I have never heard this, and have heard the opposite in that that Fiddler has improved performance.

 

What reason could be causing performance to get worse once Fiddler is installed/running?
