How to edit URL with Fiddler(script)?

Question

I want to edit a URL using fiddler. Doesn't have to be with fiddler script, but heres an approximation of how I'm doing it currently:

if (oSession.url.contains("example.com") {
  String oldUrl = oSession.url.ToString();
  Regex rgx = new Regex("1.2");
  String newUrl = rgx.Replace(oldUrl, "1.0");
}

This code is giving me a compiler error on the regex instantiation line: "The list of attributes does not apply to the current context". I'm not entirely sure what this means.

I'm also unsure how exactly to change the url.

Any ideas?

Answer 1

Just got it:

oSession.url = oSession.url.Replace("1.2","1.0");

Answer 2

You can also use

    oSession.PathAndQuery = oSession.PathAndQuery.replace('/test1/', '/changed1/');
