Modify LTM+APM inactivity timer on one url

Hi,

to insert a javascript, you can use this irule:

when RULE_INIT {
    set static::jscript {}
}

when ACCESS_ACL_ALLOWED {
     Disable the stream filter by default 
    if { [catch {STREAM::disable}] } {log local0. "Stream disable error"}
    set insertJscript 0 
    HTTP::header remove "Accept-Encoding"
    set extend_session 0
    if {[HTTP::uri] equals /myuri } {set extend_session 1}
}


when HTTP_RESPONSE { 
    if {$extend_session && ([HTTP::status] == 200) && ([HTTP::header value Content-Type] contains "text")} { 
        set insertJscript 1
        STREAM::expression "@@$static::jscript@"
        STREAM::enable
    }
    if {[HTTP::header exists "Transfer-Encoding"]} {
        HTTP::payload rechunk
    }
}


when STREAM_MATCHED {
     Once we've hit one match, disable the stream filter for the rest of the response
    if { $insertJscript} {
        log local0. "Session Closed detection : Javascript inserted"
        STREAM::disable
    }
}

then, add the following script file in APM hosted content with private properties (I do not remember the real keyword):

function detectSessionClosed()
{
    var rq = new XMLHttpRequest();
    rq.open("GET","/public/share/myjavascript.js",false);
    rq.send(null);
    if (rq.status === 302) {
      window.location.assign("/vdesk/hangup.php3");
    }
}

setInterval( detectSessionClosed, 600000);

this script try to download itself every 10 minutes until the user leave the page.
