httpRouting.url.blacklist variable

Products

• CA API Gateway

Issue/Introduction

While running a trace in Policy Manager, I see the variable "httpRouting.url.blacklist".  Is this documented anywhere?  I can't seem to find anything.

The screenshot that shows this. 

Environment

Release : 10.x

Resolution

The variable httpRouting.url.blacklist is defined and used internally by gateway.   It is used when the failover strategy is configured.  When an IP was failed, it is added to the blacklist and it will not retry that ip for centain time.  The cluster property io.failoverServerRetryDelay controls the delay before the Gateway retries a failed server. The default is to wait 15 minutes when using the "Ordered Sticky with Failover" strategy. 

The information for route via http connection configuration is here:
