location ^~ /replies/ {
     root /persist/cluster/;
     index message.xml;
     if ($uri ~ /replies/(......../././././([^/]+))) {
         set $message_path '/persist/cluster/replies/$1';
         set $reply_token $2;
     }
     if ($uri ~ header.*$) {
         error_page 404 /templates/default/header.gif;
     }
     if ($uri ~ footer.*$) {
         error_page 404 /templates/default/footer.gif;
     }
     include /opt/nginx/etc/fastcgi_params;

     if ($uri ~ /send$) {
         fastcgi_pass unix://var/run/sock/fcgi-reply.sock;
     }

     xslt_stylesheet /var/www/layouts/layout1/template.xsl  
reply_token 
='$reply_token':message_path='$message_path':status='$arg_status';
     xslt_stylesheet /var/www/layouts/layout2/template.xsl  
reply_token 
='$reply_token':message_path='$message_path':status='$arg_status';

     xslt_types text/xml;
}


And my FastCGI daemon that listens to that socket uses XML::LibXML to  
create its response, and its content-type is text/xml.  And all I get  
is the plain XML back, unaltered by XSLT.  Any ideas?
