ASP.NET middleware invoke another action - asp.net

Question

with ASP.NET 6 Web API project, i write a middleware to test action invoke.
public class RequestResponseMiddleware
{
private RequestDelegate _next;
public RequestResponseMiddleware(RequestDelegate next)
{
this._next = next;
}
public async Task Invoke(HttpContext context)
{
// need server side url rewrite
if (context.Request.Path.HasValue && context.Request.Path == "/weatherforecast/Test")
{
context.Request.Path = PathString.FromUriComponent("/weatherforecast/User");
context.SetEndpoint(endpoint: null);
var routeValuesFeature = context.Features.Get<IRouteValuesFeature>();
if (routeValuesFeature is not null)
{
routeValuesFeature.RouteValues = null!;
}
}
await _next.Invoke(context);
}
}
When client post to https://localhost:7290/weatherforecast/Test, i want it will invoke method /weatherforecast/User".
When using method context.Response.Redirect, method /weatherforecast/User will be inovked. but the request will case another url redirect.
Is it possile direct inovke /weatherforecast/User at server side.
---update---
I have downloaded asp.net core source code ,and checked out the RewriteMiddleware code, and it seams reset request.Path , likes
context.Request.Path = PathString.FromUriComponent("/weatherforecast/User");
context.SetEndpoint(endpoint: null);
var routeValuesFeature = context.Features.Get<IRouteValuesFeature>();
if (routeValuesFeature is not null)
{
routeValuesFeature.RouteValues = null!;
}
then call
_next.Invoke(context);
but ,it not works.

In your case, I think you want to use url rewrite instead of url redirect, check this Docs to learn difference. So you can use rewrite middleware to achieve it.
var rewrite = new RewriteOptions()
.AddRewrite("weatherforecast/Test", "weatherforecast/User", true);
app.UseRewriter(rewrite);
In above middleware, If url contains weatherforecast/Test, Project will invoke weatherforecast/User at server side directly.
