Persist Cookie and Domain Modification iRule question

Here is my first ever attempt at some F5 coding learning from what you started with nitass.

Am I even close?

[root@ve10:Active] config  b virtual foo_website list
 Website No.1 - https://www.foo.com.au/Login/Something
virtual foo_website {
   snat automap
   pool foo
   destination 172.28.19.252:443
   ip protocol 6
   rules redirect
   profiles {
      clientssl {
         clientside
      }
      http {}
      tcp {}
   }
}
 iRule No.1 - https://www.foo.com.au/Login/Something redirecting to https://as.abc.com.au/Login/Something
[root@ve10:Active] config  b rule redirect list
rule redirect {
   when HTTP_REQUEST {
        if { [HTTP::host] equals "www.foo.com.au" and [HTTP::uri] starts_with "/Login/Something" } {
  HTTP::redirect "https://as.abc.com.au/Login/Something [HTTP::host][HTTP::uri]"
  }
}
 
 
[root@ve10:Active] config  b virtual abc_website list
 Website No.2 - https://as.abc.com.au/Login/Something
virtual abc_website {
   snat automap
   pool foo
   destination 172.28.19.253:443
   ip protocol 6
   rules setcookie
   profiles {
      clientssl {
         clientside
      }
      http {}
      tcp {}
   }
}
 iRule No.2 - If https://as.abc.com.au/Login/Something then set cookie called setRequestAuthcontext with cookie value of SOMEKEY in the *.abc.com.au domain.  Once the cookie is set then redirect back to https://www.foo.com.au/TheApplication
[root@ve10:Active] config  b rule setcookie list
rule setcookie {
   when HTTP_REQUEST {
  set mod_ck 0
  if { [HTTP::host] equals "as.abc.com.au" and [HTTP::uri] starts_with "/Login/Something" } {
    set mod_ck 1
    HTTP::redirect "https://www.foo.com.au/TheApplication [HTTP::host][HTTP::uri]"
  }
}
when HTTP_RESPONSE {
  if { $mod_ck } {
    HTTP::cookie insert name "setRequestAuthContxt" value SOMEKEY domain "abc.com.au"
  }
}
}
