Rewrite URLs in FiddlerScript

[Alex]

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!

Hello Alex,

 

You can use Fiddler AutoResponder or FiddlerScript to redirect specific requests and create entirely custom responses or both simultaneously. Refer to the following articles for examples of how to use FiddlerScript:

Thank you for your suggestions! Based on my initial example (if anyone needs something like this), I came up with this code:

if ((oSession.fullUrl.match(/website.com\/\?sid=...$/)) && (oSession.isHTTPS)) {
  oSession.fullUrl = oSession.fullUrl.replace(/\?sid=...$/, "");
}

Add it to CustomRules.js ('OnBeforeRequest' section), and it will work great!
