Hi Mr__T so you are just wanting to rewrite the Host header in the communication from client->BIG-IP->server, but not issue a redirect, correct? You can do that in an LTM policy or in an iRule.
ltm policy host_rewrite {
last-modified 2023-09-19:14:47:44
requires { http }
rules {
host_rewrite_all_traffic {
actions {
0 {
http-header
replace
name Host
value new.fqdn.com
}
}
}
}
status published
strategy first-match
}
when HTTP_REQUEST priority 500 {
HTTP::header replace host "new.fqdn.com"
}
Note that this is not rewriting the location headers being returned from the server, and is assuming they are a) returning the original fqdn and b) are fine receiving a rewritten host. If that's the not the case, you'll need to do some more work. Post back with more details if necessary. HTH...Jason
