Dear All,
I am using Apache 2.4.15 as a reverse proxy for back-end weblogic 12c.

My requirement is to queue up connections/requests in Apache when the back-end weblogic 12c server is overloaded and then release the connection when capacity is available. 

is this possible to achieve in Apache 2.4 proxy?

Your input is much appreciated.

Apache 2.4.15 (proxy)
weblogic 12.1.3 (content server)
Red Hat Linux 7.2

Regards,
Vel
