This Emacs addon is useful for interactive testing and debugging hand-written HTTP requests:
http-twiddle-mode with M-x.C-c C-c (re)sends the request.(C-u C-c C-c to change the destination or port.)
The request can either be written from scratch or you can paste it from a snoop/tcpdump and then twiddle from there.
The mode will also activate automatically when opening a filename ending with .http-twiddle.
Try M-x http-twiddle-mode-demo in Emacs for a simple get-started example.
If the Content-Length header is not written out (like in the examples below) it'll be added automatically on send.
GET /user/bob/ HTTP/1.1
Host: example.com
[blank line here]
POST /user/create/ HTTP/1.1
Host: example.com
Content-Type: text/xml
Connection: close
<user><name>Bob</name><email>bob@example.com</email></user>
