Single Configurator with iframes (changes every x seconds) creating new session each change

[jmc1]

Hi,

New to the world of Qlik Sense Intregration, a recent request being able to present some of our departmental dashboards on TV screens around the office - the technical side of which we have all resolved. 

My problem i'm faced with is each time the html/js calls the iframe (only variation being the Region selection) it creates a new session each time, so being in 30 secs cycles this is a new session for this user every 30 secs. 

Is there a better way to accommodate this scenario where only the selection is timed and therefore not creating a new session each cycle?

Example code:

TV DEPARTMENTAL KPI

/* Change body background-color to change fade out color. */
body.siteshow { margin:0; padding:0; background-color:#ffffff; }
#menu
{
    font-family:Arial;
    font-size:9pt;
    display:none;
    opacity:0.00;
    -mozopacity:0.00;
    filter:alpha(opacity=0);
    position:absolute;
    top:10px;
    left:10px;
    padding:5px;
    background-color:#000000;
    color:#FFFFFF;
    border:3px dotted #999999;
}
#menu a { color:#ffffff; }
#menu a:hover { text-decoration:none; }
#title { font-size:11pt; font-weight:bold; letter-spacing:2; }
#slides { font-size:9pt; line-height:16pt; }
.button { width:60px; font-size:9pt; letter-spacing:1; }
