From September 11th, 2013 to February 8th, 2018, 50% user give 5-star rating, 25% user give 3-star rating, 25% user give 2-star rating. for Header-Editor chrome extension.
If you set a header it works the first time (on the server, you can see the header arriving). But then, if you alter the header value, it still sends the original value. It kept sending a particular value even after I deleted that header. Maybe you are supposed to restart the browser after changes but I'm not going to do that.
Adding request headers works. but not response headers.
Super!
Simple to use and works perfectly.
