The HTTP Proxy Layer

The tests mapped to this layer monitor the availability, responsiveness, and overall performance of the IIS web server on which Exchange 2013/2016 operates. In addition, these tests:

• Measure the efficiency of the proxy functionality of the CAS server,
• Monitor cache usage and assess its impact on the proxy functionality;
• Pinpoint application pools with poor processing power
