Inline ASE

In the inline deployment mode, API Security Enforcer (ASE) sits at the edge of your network to receive the application programming interface (API) traffic.

ASE can be deployed behind an existing load balancer such as Amazon Web Service (AWS) ELB. ASE deployed at the edge of the data center terminates SSL connections from API clients. It then routes the requests directly to the correct destination APIs and app servers such as Node.js, WebLogic, Tomcat, PHP, etc.

To configure ASE to work in Inline mode, set the mode=inline in the ase.conf file.

Some load balancers (for example, Amazon Web Services (AWS) ELB) require responses to keep alive messages from all devices receiving traffic. In an inline mode configuration, ASE should be configured to respond to these keep alive messages by updating the ase_health variable in the ase.conf file. When ase_health is set to true, load balancers can perform an ASE health check using the following URL: http(s)://<ASE Name>/ase, where <ASE Name> is the ASE domain name. ASE will respond to these health checks.
