How can I set a cookie in a request using Fiddler?

Question

I need to set a cookie before I issue a request to a Web site using Fiddler. How do I do this?

Answer 1

To do this using the FiddlerScript engine, add the following code into the onBeforeRequest method:

oSession.oRequest["Cookie"] = (oSession.oRequest["Cookie"] + ";YourCookieName=YourCookieValue");

This will preserve any other cookies that have been set.
