Hi Geneilson,

Thank you for providing the code snippet. Although, I am unable to fully understand the issue from the provided code. For example, I can not to see if this is modifying a request or response. In order to fully understand the issue, I will need the following information.

1. Which Fiddler Event Handler this is located in.

2. If there is a specific error you are receiving.

3. If there  is a specific line that isn't working or if the traffic is not modified at all.

Once I have the above information, I will be able to investigate in more detail. For additional information, see the Modify Traffic Reference.

In the meantime, please let me know if you need any additional information. Thank you for using the fiddler forums.
