You can use your reverse proxy to provide a single point of authentication for all HTTP requests. You can place your reverse proxy in an internet facing DMZ, but hide your web servers inside a non-public subnet. ![]() There are specialized load balancing products available, but many general purpose reverse proxies also provide load balancing functionality.Ī reverse proxy can hide the topology and characteristics of your back-end servers by removing the need for direct internet access to them. It’s such a common function that load balancing reverse proxies are usually just referred to as ‘load balancers’. This can work on a simple round-robin basis, or if you have statefull web servers (it’s better not to) there are session-aware load balancers available. Here the proxy routes incoming HTTP requests to a number of identical web servers. This is the reverse proxy function that people are most familiar with. Having a point at which you can inspect, transform and route HTTP requests before they reach your web servers provides a whole host of benefits. It accepts HTTP requests, provides various services, and forwards the requests to one or many servers. This is especially true if you have a distributed service oriented architecture with multiple HTTP endpoints that appear and disappear frequently.Ī reverse proxy is server component that sits between the internet and your web servers. This approach is simple and straightforward for small sites, but is hard to scale, both in terms of performance, and in terms of managing the complexity of a large complex application. ![]() This includes caching, SSL termination, authentication, serving static files and compression. All the functionality needed to produce the web site is embodied in a single server. HTTP requests from a browser or web service client are routed directly to IIS which also hosts the ASP.NET worker process. ![]() A typical ASP.NET public website hosted on IIS is usually configured in such a way that the server that IIS is installed on is visible to the public internet.
