What are the risks associated with using the Request Manager service?

Having the Request Manager service active can cause 'invalid server' or 'server not licensed' errors.

Request Manager uses configured rules to perform the following tasks when it encounters requests:

• Deny potentially harmful requests from entering a SharePoint farm.
• Route good requests to an available server.
• Manually optimize performance.

Information that administrators or an automated process provide to Request Manager determine the effectiveness of routed requests.

If using the "Request Manager service", be aware that it effectively operates as a load balancer and it needs to be correctly configured to include only the web front end servers. For more information, see Configure Request Manager in SharePoint Server 2013 in Microsoft TechNet.

 

Request Manager is functionality in SharePoint Server 2013 that enables administrators to manage incoming requests and determine how SharePoint Server 2013 routes these requests.
