Install .NET 6 if not already installed from https://dotnet.microsoft.com/download Android Tools In YARP, it is to be used to gain more control over outgoing connections and for more efficient processing of headers. Microsoft has a large number of teams that write a reverse proxy for their services themselves or look for solutions to map the tasks mentioned above. Backend request for this example looks like https://localhost:<<5001-or-5002>>/<>. The back-end server can be relieved of load by shifting tasks to the reverse proxy. The key differentiator for YARP is that it's been designed to be. On GitHub, a full working sample application is available. When it comes to microservice architectures, multiple endpoints often have to be combined to reduce complexity for consuming clients. One policy is set per route and the rest is handled by the existing ASP.NET Core authentication and authorisation components. microservices reverse proxy . Basically, think of NGINX or Ocelot. Accordingly, the origin of the request is still known after the reverse proxy is routed in the back-end via the added header information this is not the case with classic reverse proxies. Subsequent requests can then be processed with the data from the cache, thus increasing throughput. It utilises the infrastructure of ASP.NET and .NET. Unhealthy clusters are automatically blocked through the active and passive checks, and maintenance can be performed without adversely affecting the application. Unlike the Routes section, the Clusters section contains an unordered collection of named clusters. It uses the term Routes for the request patterns and uses Clusters to represent the computers (s) to forward those requests.
