iRule - Switch IP to Host Name

Hello,

 

We have a special case were we have a customer sending traffic by IP instead of host name. Instead of https://test.f5.com/api/example there hitting us as https://37.123.55.109/api/example. This was causing an issue for us in regards to the IIS/Bindings expecting but was getting an IP. I have attached the below iRule to the bip-ip 443 virtual server and traffic seems to be flowing, I'm getting a response back from server but now I'm getting an SSL error because the url still shows the IP. Is my iRule missing anything?

 

when HTTP_REQUEST { if {[HTTP::uri] contains "api/example" } { HTTP::host } }

 

Thank you for the help!

    Would this irule help? 

    when HTTP_REQUEST {
  if { ( [HTTP::host] eq "37.123.55.109" ) and 
      ( [HTTP::uri] starts_with "/api/example" ) } {
    HTTP::respond 301 Location "https://test.f5.com[HTTP::uri]"
    }
}

    Not got my lab fired up so would need to verify syntax and test.

    Hope this helps,
