If you have a blog hosted at subdomain.myqwik.blog and you want it to appear under a subdirectory like www.mydomain.com/blog in your ASP.NET application, you can achieve this with URL Rewriting.
We’ll cover different scenarios depending on how your ASP.NET project is hosted:
1. Using Nginx (Linux Reverse Proxy)
2. Using IIS with URL Rewrite Module
3. Programmatic Solution with ASP.NET Core Middleware
1. Using Nginx as a Reverse Proxy (For Linux Hosting)
If your ASP.NET Core app runs on a Linux server (e.g., Ubuntu), and you are using Nginx as a reverse proxy, you can set up rewrite rules to serve the blog under /blog.
Step-by-Step Configuration:
1. Access your Nginx Configuration File
Open your Nginx configuration file for your domain. For example:
sudo nano /etc/nginx/sites-available/mydomain.com
2. Add the Reverse Proxy Rules
Add the following configuration inside the server block:
server {
listen 80;
server_name www.mydomain.com;
# Reverse proxy for /blog
location /blog {
proxy_pass https://subdomain.myqwik.blog/blog;
proxy_set_header Host subdomain.myqwik.blog;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
location / {
proxy_pass http://localhost:5000; # Your ASP.NET Core application
}
}
• proxy_pass: Passes requests for /blog to https://subdomain.myqwik.blog/blog.
• proxy_set_header Host: Ensures the host header is forwarded correctly.
3. Restart Nginx:
Restart Nginx to apply the changes:
sudo systemctl restart nginx
What Happens:
Requests to www.mydomain.com/blog are transparently proxied to subdomain.myqwik.blog/blog.
2. Using IIS with URL Rewrite Module (Windows Hosting)
If your ASP.NET project is hosted on a Windows server using IIS, you can use the URL Rewrite Module to achieve the same result.
Step-by-Step Configuration:
1. Install the URL Rewrite Module
• Download and install the IIS URL Rewrite Module if it’s not already installed:
2. Edit Your web.config File
Open your ASP.NET project’s web.config file and add the following rewrite rules:
<configuration>
<system.webServer>
<rewrite>
<rules>
<!-- Redirect /blog to subdomain.myqwik.blog/blog -->
<rule name="Rewrite Blog Root" stopProcessing="true">
<match url="^blog$" />
<action type="Rewrite" url="https://subdomain.myqwik.blog/blog" />
</rule>
<!-- Redirect /blog/* to subdomain.myqwik.blog/blog/* -->
<rule name="Rewrite Blog Subpaths" stopProcessing="true">
<match url="^blog/(.*)" />
<action type="Rewrite" url="https://subdomain.myqwik.blog/blog/{R:1}" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
• The first rule rewrites requests to /blog.
• The second rule rewrites all subpaths under /blog to the corresponding paths on subdomain.myqwik.blog.
3. Restart IIS:
Use the IIS Manager or run the following command in the terminal:
iisreset
3. Programmatic Solution Using ASP.NET Core Middleware
If you prefer handling this directly in your ASP.NET Core project, you can use the URL Rewrite Middleware.
Step-by-Step Configuration:
1. Install Required Package:
If you don’t already have the Microsoft.AspNetCore.Rewrite package, install it using NuGet:
dotnet add package Microsoft.AspNetCore.Rewrite
2. Add Rewrite Rules in Startup.cs or Program.cs:
Modify your application’s pipeline to include URL rewriting:
using Microsoft.AspNetCore.Rewrite;
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
var rewriteOptions = new RewriteOptions()
.AddRewrite("^blog$", "https://subdomain.myqwik.blog/blog", skipRemainingRules: true)
.AddRewrite("^blog/(.*)", "https://subdomain.myqwik.blog/blog/$1", skipRemainingRules: true);
app.UseRewriter(rewriteOptions);
app.UseRouting();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
endpoints.MapRazorPages();
});
}
• AddRewrite: Adds a rewrite rule where requests to /blog and /blog/* are redirected to https://subdomain.myqwik.blog.
3. Run Your Application:
Start your application, and the middleware will handle rewriting /blog paths.
Testing Your Setup
Once you’ve configured the rewrite rules:
1. Go to www.mydomain.com/blog.
2. Verify that content from subdomain.myqwik.blog/blog is displayed.
3. Test subpaths like www.mydomain.com/blog/sample-post to ensure they work correctly.
Which Method Should You Choose?
• Use Nginx if your ASP.NET Core project is hosted on a Linux server. It’s lightweight and highly performant for reverse proxying.
• Use IIS with web.config if your project is hosted on a Windows Server.
• Use ASP.NET Core Middleware if you want to handle everything programmatically within your application.
By following these steps, you can successfully host your qwik.host blog under a /blog subdirectory while keeping the blog content at subdomain.myqwik.blog. Let me know if you encounter any issues or need further clarification! 🚀
