URL redirect with multiple FQDNs

I am trying to define an iRule which will match any domain, adding www prefix and passing on. For example, if a user browses to http://abc.com or https://abc.com, redirects to https://www.abc.com. Same for def.com, jkl.com, etc.

I tried adding this:

 when HTTP_REQUEST {
    if { [string tolower [HTTP::host]] contains"www" } {
        HTTP::redirect "https://www[HTTP::host][HTTP::uri]"
    }
    else {[HTTP::redirect] "https://www.[HTTP::host][HTTP::uri]"}
}

but it broke my test sites. Prefer to avoid specifying FQDNs as I need to match 70+ sites.

What am I missing?

Thank you

    Slightly modified the iRule.

    when HTTP_REQUEST {
     if { [string tolower [HTTP::host]] contains"www" } {
        HTTP::redirect "https://[getfield [HTTP::host] ":" 1][HTTP::uri]" }
     else { HTTP::redirect "https://www.[getfield [HTTP::host] ":" 1][HTTP::uri]" }
       }
