I\'d like to pass a raw HTTP request like:
GET /foo/bar HTTP/1.1 Host: example.org User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; fr; rv:1.9.2.8
Note that neither of these solutions would work if your need httpS instead of http. In this case you can send it this way:
$ cat raw.http | openssl s_client -connect server:443
