I\'ve been looking for a way to alter a XHR request made in my browser and then replay it again. Say I have a complete POST request done in my browser, and the only thing I want
My two suggestions:
Chrome's Postman plugin + the Postman Interceptor Plugin. More Info: Postman Capturing Requests Docs
If you're on Windows then Telerik's Fiddler is an option. It has a composer option to replay http requests, and it's free.
