Tool to view response headers [closed]

Answer 1

If you aren't looking to do it on your machine, you can use any number of online applications that do it for you.

1. Rex Swain's HTTP viewer
2. http://web-sniffer.net/: This one is a bit more flexible with regard to the app layer protocol (HTTP/S)
3. Ask Apache: This one lets you customize your request a lot more.
