ASP.net 5 404 error when hosting as an application inside website

[raymak23]

Hello,

There appears to be an issue hosting asp.net 5 mvc 6 application when hosting an application as an application inside website.

Below is screenshot contains my hosting environment. I have a ps application inside Admin website. When I browse http://localhost:8084/ps, I get 404 page in the browser.

Then I setup a new website called ps with port 8085 and configured it to point to application wwwroot path, and when I browse the URL http://localhost:8085/ I am able to see the landing page of the application.

See aspnet/IISIntegration#14

@Tratcher Can this be related to aspnet/Mvc#3769?

[Tratcher]

@javiercn not for a normal browser request to the home page. It's probably aspnet/IISIntegration#14.

Thanks guys, I will give it a try.

So I followed along with comments and I found something that I thought would work. I added environment variable in web.config that is in wwwroot folder. Please see below config settings:

<httpPlatform processPath="..\approot\web.cmd" arguments="" stdoutLogEnabled="true" stdoutLogFile="..\logs\stdout.log" startupTimeLimit="3600">
        <environmentVariables>
            <environmentVariable name="HTTP_PLATFORM_APPL_PATH" value="/ps" />
        </environmentVariables>
</httpPlatform>

Then I recycled the app pool and performed IISREST, and when I browse the application localhost:8084/ps I still get 404 error.

In stdout.log file I see below log created:

Hosting environment: Production
Now listening on: http://localhost:19684
Application started. Press Ctrl+C to shut down.

I also checked httpPlatform

Are you using the current RC2 packages described here? aspnet/IISIntegration#52 (comment)

[raymak23]

Nope, I am using RC1. Please see below dependencies from project.json file.

"dependencies": {
    "Microsoft.AspNet.Mvc": "6.0.0-rc1-final",
    "Microsoft.AspNet.Mvc.Core": "6.0.0-rc1-final",
    "Microsoft.AspNet.Server.Kestrel": "1.0.0-rc1-final",
    "Microsoft.AspNet.StaticFiles": "1.0.0-rc1-final",
    "Microsoft.Extensions.Logging.Debug": "1.0.0-rc1-final",
    "Microsoft.AspNet.Mvc.TagHelpers": "6.0.0-rc1-final",
    "Microsoft.Net.Http.Server": "1.0.0-beta5",
    "dnx-clr-win-x64": "1.0.0-rc1-update1",
    "Microsoft.AspNet.IISPlatformHandler": "1.0.0-rc1-final"
  }

The web.config workaround only applies to the latest RC2 packages. For RC1 you need to use the Map workaround: aspnet/IISIntegration#14 (comment)

[raymak23]

Thanks @Tratcher. Since RC2 is not production ready yet. I will continue to use RC1. So I applied below settings in startup.cs file and now I am getting 500 error.

public void Configure(IApplicationBuilder app, ILoggerFactory LoggerFactory, IHostingEnvironment env)
        {
            app.Map("/ps", (app1) => this.Configure1(app1, env, LoggerFactory));
            LoggerFactory.AddDebug(LogLevel.Warning);
            app.UseIISPlatformHandler();
            app.UseStaticFiles();

            app.UseMvc(config =>
            {
                config.MapRoute(
                    name: "Default",
                    template: "{controller}/{action}/{id?}",
                    defaults: new { controller = "App", Action = "Index" }
                    );
            }); // Use MVC from Dependency.
        }

        private void Configure1(IApplicationBuilder app1, IHostingEnvironment env, ILoggerFactory loggerFactory)
        {

        }
        } 

I also tried this as well:

public void Configure(IApplicationBuilder app, ILoggerFactory LoggerFactory, IHostingEnvironment 
env)
        {
            app.Map("/ps", (app1) => this.Configure(app1, env, LoggerFactory));
            LoggerFactory.AddDebug(LogLevel.Warning);
            app.UseIISPlatformHandler();
            app.UseStaticFiles();

            app.UseMvc(config =>
            {
                config.MapRoute(
                    name: "Default",
                    template: "{controller}/{action}/{id?}",
                    defaults: new { controller = "App", Action = "Index" }
                    );
            }); // Use MVC from Dependency.
        }

        }

        private void Configure1(IApplicationBuilder app1, IHostingEnvironment env, ILoggerFactory loggerFactory)
        {
            LoggerFactory.AddDebug(LogLevel.Warning);

            app.UseStaticFiles();

                    defaults: new { controller = "App", Action = "Index" }
                    );
            }); // Use MVC from Dependency.
        }
