ASP.NET Core Web Site Publishing Problem from Subfolder

Question

Hello,

I am developing a website using Visual Studio with [ASP.NET] Core MVC (C#) .NET 8 and I have published my site. My project files are located in the httpdocs/frez folder of the server. But normally web files should be in the httpdocs folder. When I put my project files in the httpdocs folder the site works fine, but I need to keep these files in the httpdocs/frez folder.

I made the following edits to Program.cs to make it work in this folder structure:

builder.WebHost.UseWebRoot(Path.Combine(Directory.GetCurrentDirectory(), “httpdocs”, “frez”));

I also edited my Web.config file as follows:

<?xml version=“1.0” encoding=“utf-8”?>

<configuration>

<location path=“.” inheritInChildApplications=“false”>

<system.webServer>

<handlers>

<add name=“aspNetCore” path=“*” verb=“*” modules=“AspNetCoreModuleV2” resourceType=“Unspecified” />

</handlers>

<aspNetCore processPath=“dotnet” arguments=“./frez/project.dll” stdoutLogEnabled=“true” stdoutLogFile=“./logs/stdout” hostingModel=“inprocess” />

<rewrite>

<rules>

<rule name=“Rewrite to frez folder” stopProcessing=“true”>

<match url=“(.*)” />

<action type=“Rewrite” url=“/{R:1}” />

</rule>

</rules>

</rewrite>

</system.webServer>

</location>

</configuration>

Although I made these arrangements, my website is not working. Can you help me to solve the problem?

Hi @Enes Gündoğdu,

This is my structure in IIS site. In my scenario, the web.config under the httodocs takes effect, and the web.config under the frez folder does not ...

Program.cs

//var builder = WebApplication.CreateBuilder(args);
//builder.WebHost.UseWebRoot(Path.Combine(Directory.GetCurrentDirectory(), "httpdocs", "frez"));
//Console.WriteLine(Path.Combine(Directory.GetCurrentDirectory(), "httpdocs", "frez"));
using Microsoft.Extensions.FileProviders;
string basedir = AppDomain.CurrentDomain.BaseDirectory;
WebApplicationOptions options = new()
{
    ContentRootPath = basedir,
    Args = args,
    WebRootPath = Path.Combine(basedir, "wwwroot")
};
var builder = WebApplication.CreateBuilder(options);
// Add services to the container.
builder.Services.AddControllersWithViews();
var app = builder.Build();
// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Home/Error");
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();
}
app.UseHttpsRedirection();
//app.UseStaticFiles();
app.UseStaticFiles(new StaticFileOptions
{
    FileProvider = new PhysicalFileProvider(Path.Combine(basedir, "wwwroot")),
    RequestPath = "/frez" 
});
app.UseRouting();
app.UseAuthorization();
app.MapControllerRoute(
    name: "default",
    pattern: "{controller=Home}/{action=Index}/{id?}");
app.Run();

httpdocs/web.config

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath="dotnet" arguments=".\frez\WebApplication18.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="inprocess" />
      <rewrite>
      <rules>
        <rule name="Add Frez Prefix to Static Files" stopProcessing="true">
          <match url="^lib/(.*)" />
          <action type="Rewrite" url="/frez/lib/{R:1}" />
        </rule>
        <rule name="Add Frez Prefix to CSS and JS Files" stopProcessing="true">
          <match url="^(css|js)/(.*)" />
          <action type="Rewrite" url="/frez/{R:1}/{R:2}" />
        </rule>
        <rule name="Add Frez Prefix to Other Static Files" stopProcessing="true">
          <match url="^(images|fonts)/(.*)" />
          <action type="Rewrite" url="/frez/{R:1}/{R:2}" />
        </rule>
      </rules>
    </rewrite>
    </system.webServer>
  </location>
</configuration>

Answer 2

When I open the website, this is what it says on the screen;

This page is not working

website.com is unable to handle this request at this time.

HTTP ERROR 500

Answer 3

There are php sites in other folders in the httpdocs folder of the server. Could it be conflicting with these sites?

Answer 4

Why don't you deploy your ASP.NET Core app as the site of IIS according to the Microsoft tutorial Publish an ASP.NET Core app to IIS?
