README

A flexible Neos CMS package for configuring domain and path-based HTTP redirects using plain strings or regex patterns.

Features

• Domain-based redirects: Redirect entire domains to new locations
• Regex support: Use regex patterns for both domain matching and path transformations
• Path transformation rules: Define multiple rules per domain with regex patterns
• Custom status codes: Configure individual status codes (301, 302, 307, etc.) per redirect
• Capture group support: Use regex capture groups ($1, $2, etc.) in replacements
• Flexible configuration: Works with plain domain strings or complex regex patterns
• HTTP Middleware: Runs after Neos redirect middleware for optimal performance

Installation

Install via Composer:

composer require kaufmanndigital/domainredirection

Configuration

Add your redirect configuration to your Settings.yaml:

KaufmannDigital:
  DomainRedirection:
    redirects:
      - domainPattern: 'old-domain.com'
        target: 'https://new-domain.com'
        statusCode: 301

Usage Examples

1. Simple Domain Redirect

Redirect an entire domain to a new location:

KaufmannDigital:
  DomainRedirection:
    redirects:
      - domainPattern: 'old-domain.com'
        target: 'https://new-domain.com'
        statusCode: 301

Result:

• old-domain.com → https://new-domain.com
• old-domain.com/any/path → https://new-domain.com

2. Domain Redirect with Path Preservation

Use regex to preserve and transform the path:

KaufmannDigital:
  DomainRedirection:
    redirects:
      - domainPattern: 'old-domain.com/(.*)$'
        target: 'https://new-domain.com/$1'
        statusCode: 301

Result:

• old-domain.com/about → https://new-domain.com/about
• old-domain.com/contact/form → https://new-domain.com/contact/form

3. Subdomain to Path Redirect

Redirect a subdomain to a specific path on the main domain:

KaufmannDigital:
  DomainRedirection:
    redirects:
      - domainPattern: 'blog.example.com'
        target: 'https://example.com/blog'
        statusCode: 307

Result:

• blog.example.com → https://example.com/blog
• blog.example.com/article → https://example.com/blog

4. Subdomain with Path Transformation

Redirect a subdomain and append the path to a specific location:

KaufmannDigital:
  DomainRedirection:
    redirects:
      - domainPattern: 'karriere.example.com/(.*)$'
        target: 'https://example.com/careers#$1'
        statusCode: 307

Result:

• karriere.example.com/jobs → https://example.com/careers#jobs
• karriere.example.com/apply/form → https://example.com/careers#apply/form

5. Path-Specific Rules

Define multiple rules for different path patterns on the same domain:

KaufmannDigital:
  DomainRedirection:
    redirects:
      - domainPattern: 'example.com'
        target: 'https://new-example.com'
        statusCode: 301
        rules:
          - pattern: '^/old-section/(.*)$'
            replacement: '/new-section/$1'
            statusCode: 301
          - pattern: '^/legacy/(.*)$'
            replacement: '/modern/$1'
            statusCode: 302

Result:

• example.com/old-section/page → https://new-example.com/new-section/page
• example.com/legacy/content → https://new-example.com/modern/content (302)
• example.com/other → https://new-example.com (fallback)

6. Multiple Domains with Different Rules

Configure multiple domain redirects in the same configuration:

KaufmannDigital:
  DomainRedirection:
    redirects:
      - domainPattern: 'old-site.com'
        target: 'https://new-site.com'
        statusCode: 301

      - domainPattern: 'beta.example.com'
        target: 'https://example.com/beta'
        statusCode: 307
        rules:
          - pattern: '^/test/(.*)$'
            replacement: '/testing/$1'
            statusCode: 302

Configuration Options

Main Configuration

• domainPattern (required): Domain to match. Can be:

  • Plain string: 'example.com'
  • Regex pattern: 'example.com/(.*)$'

• target (required): Target URL to redirect to

• statusCode (optional, default: 301): HTTP status code for the redirect

  • 301 - Permanent redirect
  • 302 - Temporary redirect
  • 307 - Temporary redirect (preserves HTTP method)
  • 308 - Permanent redirect (preserves HTTP method)

• pattern (optional): Regex pattern for path transformation (alternative to using regex in domainPattern)

• rules (optional): Array of path-specific rules

Rules Configuration

• pattern (required): Regex pattern to match against the path
• replacement (required): Replacement string (can include capture groups like $1, $2)
• statusCode (optional): Override status code for this specific rule

How It Works

1. The middleware checks each configured redirect in order
2. If domainPattern matches (either as plain string or regex):
   • First, it checks if any rules match the current path
   • If a rule matches, it applies the rule's transformation
   • If no rule matches, it uses the default target
3. The middleware runs after the Neos redirect middleware
4. If no redirect matches, the request continues to the next middleware
