[httperf] Request with particular host header

[Laghate, Prasanna]

How do I make a request which goes to server 1.2.3.4, but with a hostheader
"x.y.com"?

The following request:
httperf --server=1.2.3.4 --server-name="x.y.com" --uri=/index.html
--print-request

gives:
SH0:GET /index.html HTTP/1.1
SH0:User-Agent: httperf/0.8
SH0:Host: 1.2.3.4

whereas I want:
SH0:GET /index.html HTTP/1.1
SH0:User-Agent: httperf/0.8
SH0:Host: x.y.com

Thanks,
Prasanna
