I'm glad that it worked for you.<br>
<br>
Note: I call this technique "Apex Override".<br>
<br>
I believe the Apex Override technique can be used anywhere you want to <br>
selectively override a (single) FQDN.<br>
<br>
I suspect there are some more nefarious things that you can do with <br>
this, particularly if combined with DNAME. But I try to keep my hit a <br>
lighter shade of gray.<br>
