Thanks for a detailed answer, Robert. Would have any workaround?
I was thinking of embedding a hardcoded 5s delayed redirects to a gateway page into custom 500 error page.

Also, Witango has never had the functionality to do stateful failover. In fact most environments don't (by default) since it requires either a single point of reference (such as a database) or a lot of overhead. TeraScript will eventually have this feature, unfortunately, there are several steps before we get there: 1. Correcting the load balancing and (stateless) failover capabilities of the client <-> server protocol. 2. Developing a simple pooling system that can dynamically expand and shrink the pool. 3. Adding persistent variable synchronization (sharing domain and application scopes variables between pooled servers) 4. Adding user variable synchronization (sharing user scoped variables between pooled servers) We are also keen on correcting all underlying crashing issues so failover is more of an administrative function than a safeguard. All of this and lot more is on the list.

In the recent days we've formed a requirement for a stateful failover among the application servers in the array. In case of a Server crash, we want the customer to be transparently carried over to another working daemon. The way it works in our testlab, when a particular daemon crashes a visitor is presented with the custom 500 error page. The problem is, that customer doesn't get failed over to the next available Witango instance, while every subsequent new visitor gets properly routed to the next working instance by an ISAPI witango client plug-in. Is there any built-in mechanism for a transparent failover of the existing visitor sessions over to the next server in the array? Perhaps we're missing some configuration settings?
