I would like to know if it is possible to re-write the HTTP host header by F5, and send it to one server. Then, once the server response is received, re-write the HTTP host header again to the original HTTP host value and send it back to the client. Appreciate your help.
when HTTP_REQUEST {
HTTP::header replace Host "newhost.example.com"
}
when HTTP_RESPOND {
HTTP::header replace Host "oringal.example.com"
}

I don't think there's a HTTP_RESPOND event - I doubled checked the Wiki. But, I don't think even using HTTP_RESPONSE would work as there isn't a host header in the response.
Hoolio (as always) has answered a similar request here using the stream command:

Hope I'm not mistaken and hope this helps.

You're correct. Thanks for linking the other thread with the example. Gbps, if you get stuck with that example reply here with details on the iRule you're testing and what's not working.

As for the host header in the response most likely the rewrite would be for the location field if the server is redirecting the client which would rewrite the browser URL. I did not read the question too closely. Though the header replace can be done using the iRUle it could also be done using HTTP classes.
