HTTP Redirect not working

I am new to iRules and I am trying to setup an iRule to redirect some traffic. I want to do this when status 301 and 302 are returned in the headers, but for basic testing I went with just the below ...

when you request URL http://www.domain123.com/.well-known/acme-challenge/aeIswOdWkV3TlYv24PI7Nv9OYvcF0eKfyrLlVpdSW7s, the HTTP request is:

GET /.well-known/acme-challenge/aeIswOdWkV3TlYv24PI7Nv9OYvcF0eKfyrLlVpdSW7s HTTP/1.1
Host: www.domain123.com
User-Agent: Mozilla/4.0......

So following HTTP commands return:

  • HTTP::host -->
  • HTTP::uri --> /.well-known/acme-challenge/aeIswOdWkV3TlYv24PI7Nv9OYvcF0eKfyrLlVpdSW7s

So the irule must be:

when HTTP_REQUEST { 
    if {([HTTP::host] equals "www.domain123.com") } { 
        HTTP::redirect "http://www.somethingelse.com[HTTP::uri]"
    } 
}

or if you want to manage URI in condition:

    when HTTP_REQUEST { 
    if {([HTTP::host] equals "www.domain123.com") && [HTTP::uri] starts_with "/.well-known/acme-challenge/"} { 
        HTTP::redirect "http://www.somethingelse.com[HTTP::uri]"
    } 
}
