I could not located L7 things.</span><br>
<br>
</p>
<p>L7 things might be related to Octavia (only?). What I found is that HAProxy (<a href="https://www.haproxy.com/doc/aloha/7.0/haproxy/index.html" class="OWAAutoLink" id="LPlnk508325" previewremoved="true">https://www.haproxy.com/doc/aloha/7.0/haproxy/index.html</a>)
has L7 things.</p>
<p><br>
</p>
<p>It seems that in old good times that thing was not taken into the consideration.</p>
