How to Configure Apache Redirects

Apache Redirect provides simple, efficient URL redirection. It is preferred over mod_rewrite for straightforward redirect scenarios. This guide walks through the specific troubleshooting steps to diagnose and resolve redirect issues.

Before You Begin

Before you begin, be sure to have the following in place:

• A Linux server with the relevant software installed
• Access to the command line interface
• Appropriate permissions (root or sudo)

Quick Fix

Wrong

RewriteEngine On\nRewriteRule ^old$ /new [R=301,L] (overkill for simple redirect)

Wrong: Using mod_rewrite for a simple redirect

Right

Redirect 301 /old /new

Right: Using Redirect for simple path redirects

Output

Redirect configured:\n  /old → /new (301 permanent)\n  Method: mod_alias Redirect

Prevention

To avoid future issues, follow these best practices:

• Use Redirect for simple path-to-path redirects (faster than mod_rewrite)
• Use RedirectMatch for regex-based redirects
• Use 301 for permanent moves, 302 for temporary
• Use RedirectPermanent and RedirectTemp as readable alternatives
• Use Redirect 410 for permanently removed resources

DodaTech Tools

Common Mistakes with redirect

1. Misunderstanding that String is [Char] with poor performance for large text operations
2. Using foldl instead of foldl' causing stack overflow on large lists
3. Forgetting deriving (Show, Eq) on custom data types needed for debugging

These mistakes appear frequently in real-world APACHE code. DodaTech's contributors have identified these patterns through analysis of open-source projects and production systems.

Practice Exercise

Write a pure function that safely divides two integers using Maybe, then test it with edge cases like division by zero and negative numbers.

This exercise reinforces the concepts covered in this guide. Try implementing it before checking online solutions.
