connection limit on VS and redirect page

On the VS configuration there is a MAX connection limit,

 

 

As you are using http, a http_profile could specify a fallback page URL. This is normally used for when the pool is unavailable, but I'm not sure if it would trigger in this case; try it and see.

 

 

Failing this, with a bit of research the VS connection limit variable and current connections variable may be available to reference insid ethe iRule: (PSEUDO CODE BELOW, THIS IS NOT TCL)

 

when HTTP_REQUEST {

 

if [ $CURRENT_CONS > $VS_CONN_LIMIT]

 

{

 

HTTP::redirect https://my.domain/too_many_connections_page.html

 

return

 

}

 

 

or similar?
