Directing Requests Based on Priority

The NetScaler provides the priority queuing option for prioritizing client requests to serve important requests first. The NetScaler places the requests in a queue based on the configured priority, thereby providing an uninterrupted flow of transactions through dynamic traffic flows.

The priority queuing feature also lets you filter incoming HTTP traffic on the basis of categories that you create and define, and prioritize those HTTP requests accordingly. Priority queuing directs high-priority requests to the server ahead of low-priority requests, so that users who need resources for important business uses receive expedited access to your protected Web servers.

To set priority queueing on a virtual server using the NetScaler Load Balancer command line

set lb vserver <vServerName> -pq <Value>

set lb vserver Vserver-LB-1 -pq yes

To set priority queueing on a virtual server by using the GUI configuration utility
