ASP.NET Core: URL rewriting does not work with a static file

Question

app.UseRewriter(new RewriteOptions().AddRedirect("login", "login.html")); //works
app.UseRewriter(new RewriteOptions().AddRewrite("login", "login.html", false)); //doesnt work

In the second case i get error 404, page not found. Why? The file is in the wwwroot directory.

Answer 1

Be sure call app.UseRewriter before app.UseStaticFiles(), otherwise the RewriteMiddleware might be superseeded by the one in charge of the static files, which could mess up your rewrite rules:

app.UseRewriter(new RewriteOptions().AddRewrite("login", "login.html", false)); 
app.UseStaticFiles();
