Topologies
HARP runs as a forward proxy on the path between your applications and the remote APIs they call. These pages explain that topology, how it compares to an API gateway, and where HARP fits.
Forward proxy
HARP's primary topology: a forward proxy between your application and the remote APIs it calls, adding caching, resilience and observability without changing application code.
