Use _________ to redirect traffic or respond with custom messages.
Use _________ for manipulating data on HTTP requests and responses.

Question45: Scenario: A Citrix Administrator installed the compression feature on the web servers. To offload the compression on the Citrix ADC, the administrator configured the Citrix ADC appliance to remove the 'Accept Encoding' header from all HTTP client requests. However, the administrator observes that data is NOT being compressed by the Citrix ADC, even though the 'Accept Encoding' header is being removed from all requests.
What could be the cause of this issue?

A week later the administrator discovers that the ACL is no longer present on the Citrix ADC.
What could be the reason for this?

Question52: Scenario: A Citrix Administrator gives permissions to team members to access their own admin partition. This will allow them to add resources for different departments and manage them without making changes to the default Citrix ADC partition and configuration.
One team member typing to use the command line interface (CLI) to troubleshoot an authentication issue could NOT use aaad.debug. However, the team member has full permissions on the admin partition.
