Requested Web Switching Service quality. This field is meaningfull onnly in the context of Web-Switching applications (Server Load balancing, Application redirection, Firewall load balancing, etc.). If a given flow needs to be mapped to a server group, (because of WebSwitching configurations), and this flow also matches a policy rule, then the selection of the group will be determined by mapping the quality class required ny the flow to the wquality assigned to the available groups. The meaining of the class is: 0 - lowest quality 255 - highest quality. Example: A flow matches quality level of 42. two server groups are defined - one with quality class of 0, and the 2nd with quality class of 42. The flow will map to the server group with quality class 42.
