Extend SEOChecker

You can add your own URL rewrite rules to the URL rewrite module.

URL rewrite provider

A URL rewrite provider changes the URL of a request. When the URL changes, SEOChecker redirects the visitor to the new URL. This way all variants of a URL end up at one canonical URL.

To create one:

1. Reference the SEOChecker.Core package from your project.
2. Create a class that derives from UrlRewriteProvider.
3. Override RewriteUrl and change the UrlBuilder that is passed in.

SEOChecker finds your provider automatically when the site starts. Override Prio to change the order in which providers run. The default is 100.

Example: always use HTTPS

using System;
using SEOChecker.Core.Providers.UrlRewriteProviders;

/// <summary>
/// Redirects every HTTP request to HTTPS.
/// </summary>
public class HttpsRedirect : UrlRewriteProvider
{
    public override void RewriteUrl(UrlBuilder builder, UrlRewriteConfiguration config)
    {
        if (builder.Scheme.Equals("http", StringComparison.InvariantCultureIgnoreCase))
        {
            builder.Scheme = "https";
        }
    }
}
