How is iis url rewriting different from asp.net routing?


Asked by Julien Watts on Dec 14, 2021 ASP.NET



Based on the above explanation, there are the following main conceptual differences between IIS URL rewriting and ASP.NET routing: URL rewriting is used to manipulate URL paths before the request is handled by the Web server. The URL rewriting module does not know which handler will eventually process the rewritten URL.
Thereof,
In addition to these conceptual differences, there are the following functional differences between IIS URL rewriting and ASP.NET routing: The IIS URL Rewrite module can be used with any type of Web application, which includes ASP.NET, PHP, ASP, and static files.
Likewise, This means that the handler selection in the IIS pipeline is made based on the rewritten URL that is produced by the URL Rewrite module. ASP.NET routing is a request-dispatching mechanism that lets developers associate a certain URL with a handler that can process requests made to that URL.
In this manner,
ASP.NET routing is implemented as a managed-code module that plugs into the IIS request-processing pipeline at the Resolve Cache stage (PostResolveRequestCache event) and at the Map Handler stage (PostMapRequestHandler event). ASP.NET routing is configured to run for all requests made to the Web application.
Also Know,
URL Rewriting Middleware is provided by the Microsoft.AspNetCore.Rewrite package, which is implicitly included in ASP.NET Core apps. Establish URL rewrite and redirect rules by creating an instance of the RewriteOptions class with extension methods for each of your rewrite rules. Chain multiple rules in the order that you would like them processed.
