This walkthrough will guide you through how to use URL Rewrite Module and Application Request Routing (ARR) to implement a reverse proxy server for multiple back-end applications. SharePoint Server and SharePoint in Microsoft 365 can be configured in a hybrid configuration to securely combine search results and external data from Microsoft Business Connectivity Services. An optional precondition that controls whether this rule should be applied to a response.

YARP is designed with customizability as a primary scenario rather than requiring you to break out to script or rebuild the library from source. Tag filters allow you to specify that the pattern matching should be applied only within the content of certain HTML tags, thus significantly reducing the amount of data that has to be evaluated against regular expression pattern. This rule needs to replace links in the response content so in the "Matching Scope" drop down list choose "Response".

Reverse Proxy functionality is disabled by default, so you must begin by enabling it. These parentheses create a capture group, which can be later referenced in the rule by using back-references. For example, my proxy calls an api to get a valid token for this request, if I open the application insights log, it show the token request, but it doesn't show the proxy request to the destination. The following list describes the steps shown in the preceding picture. Many of the existing proxies were built to support HTTP/1.1, but with workloads changing to include gRPC traffic, they require HTTP/2 support which requires a significantly more complex implementation. What's new in 1.1? By using YARP the projects get to customize the routing and handling behavior without having to implement the http protocol.
