Issue: URL Rewrite using web.config is broken in RC2

[anwalkers]

I have tried moving the web.config to and fro and cannot get the URL rewrite to work in IIS Express from Visual Studio 2015. If there was middleware to perform what is spelled out in the web.config snippet I could punt on the web.config and selfhost. Maybe someone can point me in that direction to solve our problem.

We need to use Angular 1.x HTML 5 routing in our application and this is how we had solved it in RC1 but it doesn't work in RC2. Others are having trouble as well: http://stackoverflow.com/questions/37304113/url-rewriting-in-asp-net-core-rc2#

          </conditions>

    </rewrite>
  </system.webServer>
</configuration>

I'm going to ping @ciel on Slack, who may have a solution for this.

I'll take a look at this when I get home this evening, sure. I'm using
angular extensively with RC2. I know I've got a working demo of this in one
of my projects somewhere.

I'm not at a computer right now, but looking at your sample have you tried using "^(.*)$" as the match url? And of course, you can confirm that you've got html5mode active?

[anwalkers]

I haven't tried the regex "^(.*)$". Any links to your examples would be great!

[muratg]

@anwalkers Were you able to verify the regex suggested by @ciel?

[anwalkers]

@muratg I have not. I am on a deadline and have turned HTML5 routing off temporarily. Will tackle this when I get to the Azure WebApp deployment step. Hoping @ciel will have a link to an example along the way.

That said, any progress on getting IIS Express from VS 2015 to pay attention to URL rewriting in the web.config?

[anwalkers]

I tried the following code in my Startup.cs to do middleware URL rewrite. It works fine for the base URL, but does not support deep links into an AngularJS 1.x application with HTML5 routing enabled. It does work with HTML5 routing disabled.

Works:
Base URL: http://localhost:5000
API: http://localhost:5000/api/someApi
Library or resource: http://localhost:5000/lib/library.js
HTML5 Routing Disabled: http://localhost:5000/#/angularRoute NOTE: Deep linking works here.

Does not work:
HTML5 Routing Enabled: http://localhost:5000/angularRoute NOTE: This does work if you have loaded the application from the base URL and navigated to the route, but does not work if you have pasted the deep link with the angular route, http://localhost:5000/angularRoute, into a new browser window.

From Startup.cs:

            app.UseMvc();

            // this serves "index.html" from the wwwroot folder when 
            // a route not containing a file extension is not handled by MVC.
            app.MapWhen(context =>
            {
                var path = context.Request.Path.Value.ToLower();
                return path.Contains(".*");
            },
                branch =>
                {
                    branch.Use((context, next) =>
                    {
                        context.Request.Path = new PathString("/index.html");
                        return next();
                    });

                    branch.UseStaticFiles();
                });

Just for clarity, here is a snippet for enabling HTML5 routing in angular 1.x application. It removes the # hash based routing.

            $locationProvider
                .html5Mode(true);

@Tratcher thoughts on why this may have regressed?

I have published a simple sample app to this repository.

DELETED THIS REPO: https://github.com/anwalkers/AngularUrlRewriteAspNetCore1

This site is a vanilla ASP.Net Core 1 RC2 project using one MVC route to an index.cshtml as the root page for the site. It does not have the mapWhen function or static html in the wwwroot directory. It is checked in a broken state. You can switch it back to non-HTML5 mode by editing the site.js and a bit of markup.

It also does not have mapWhen in the Startup.cs, wasn't sure how to mix the MVC routing and the mapWhen... It does have the rewrite rules in the web.config.

@muratg @Tratcher @pan-wang @ciel Any progress or discussion on this issue?

[Tratcher]

I was able to repro this using just the UrlRewrite samples here:
http://www.iis.net/learn/extensions/url-rewrite-module/creating-rewrite-rules-for-the-url-rewrite-module
(against ANCM rather than Asp.Net 4).

I see two issues:

• Kestrel receives the request, but the url has not been modified.
• Kestrel's response is not forwarded to the client, the client only receives an empty 200 response (Content-Length: 0)

Assigning to @pan-wang to debug.
