<b>Subject:</b> [Freeswitch-users] Sending keepalives on Verto websocket<o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<div>
<div>
<p class="MsoNormal">I've switched to using Nginx to proxy Verto websockets, and have run into a small snag: by default, if Nginx doesn't read any data from a proxy backend within 60 seconds, it closes the connection, even for websockets.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">It appears the recommended solution is to have the server send some kind of regular keepalive. I poked around in mod_verto.c and found a 'request.keepalive' variable, but I'm unclear how to set that in the request, and/or if it even accomplishes
what I'm wanting.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I've solved the issue for now by periodically sending a JSON RPC 'echo' request along the websocket every 50 seconds, and the reply from the server is enough to keep the connection open. This is fine, but I am curious if there's a way to
do it just from the server side, and if not, if it's worth it to add a setting to enable that functionality?<o:p></o:p></p>
