Trying iRules, new to Ver 11

I added the following value

 

 

Local Traffic ›› iRules : Data Group List ›› rewrite_domains

 

and created the iRule

 

 

when HTTP_REQUEST {

 

Check to see if this is a new domain that needs to be silently re-written

 

set newURI [class match -value [HTTP::host] eq rewrite_domains]

 

if {$newURI ne ""} {

 

If it is, re-write the URI to the class matched value, and the host header to the old domain

 

HTTP::uri $newURI

 

HTTP::header replace "Host" "staging.site.com"

 

unset newURI

 

If it's not, check to see if it's someone accessing the old domain incorrectly

 

} elseif {[HTTP::host] eq "staging.site.com"} {

 

If it is someone accessing the old domain format, redirect them to the new domain

 

set redirDom [class match -value [HTTP::path] starts_with redirect_urls]

 

if {$redirDom ne ""} {

 

HTTP::redirect "https://$redirDom"

 

unset redirDom

 

}

 

}

 

}

 

 

no errors but I cannot make it to change the host when I type
