Configure Apache to propagate servlet down condition back to load balancer

Bruce Atherton <bruce@xxxxxxxxxxxxx> · Thu, 01 May 2008 12:13:59 -0700

I have the following configuration:

   BIG-IP   ->  Apache HTTPD  ->  Servlet Container
    Load    ->  Apache HTTPD  ->  Servlet Container
  Balancer  ->  Apache HTTPD  ->  Servlet Container

The Apache HTTPD instance serves up static content and translates HTTPS 

requests into HTTP. Dynamic content is proxied to a Servlet Container 

running an application.

My problem is that when one of the servlet containers seizes up, the 

BIG-IP box doesn't take the Apache instance out of circulation. Instead, 

users are continually connected to non-responsive servlets.

Is there any way to configure Apache so that it is identifies itself as 

unavailable to the BIG-IP box if it finds that all proxy requests are 

failing?

Thanks for any help.
