Our local policy demands the rejection of any query; we do this as follows:<br>
if ($is_args) { return 301 /; }<br>
<br>
The introduction of Thunderbird autoconfiguration demands an exception to<br>
the above policy, because of<br>
"GET<br>
/.well-known/autoconfig/mail/c<wbr>onfig-v1.1.xml?emailaddre=unam<wbr>e%<a href="http://40example.com" rel="noreferrer" target="_blank">40example.com</a>".<br>
<br>
The resulting rule would be<br>
<br>
if (($is_args) && ($args !~ emailaddress=.+%40[a-zA-Z0-9\.<wbr>\-]+)) { return<br>
301 /; }<br>
<br>
The rule does not work, because nginx does not parse the AND condition.<br>
<br>
Of course, you cannot just remove $is_args, because $args is usually empty.<br>
<br>
<br>
The alternative would be if ($args ~ emailaddress=.+%40[a-zA-Z0-9\.<wbr>\-]+)) {<br>
allow all; } else { return 301 /; },<br>
but nginx does not parse if-then-else statements.<br>
<br>
Are we stuck in the cage?<br>
