دليل إعداد إعادة التوجيه في لوحة الويب

لوحة الويب is one of the most widely deployed web servers, and redirect configuration is a routine part of running it. The two main tools — return and rewrite — are often confused, leading to inefficient or broken configs.

.htaccess و mod_rewrite

return (recommended)

return 301 https://example.com;

• ✅ Fast — sends the HTTP response directly, no regex engine involved
• ✅ Simple syntax, hard to get wrong
• ✅ Official recommendation for most redirect use cases
• ❌ Can't capture and reuse URL segments

rewrite (powerful but slower)

rewrite ^/old-path/(.*)$ /new-path/$1 permanent;

• ✅ Supports regex capture groups
• ✅ Can transform URL structure
• ❌ Slower than return
• ❌ Complex syntax, easy to create infinite loops

أمثلة أساسية

301 permanent redirect

server {
    listen 80;
    server_name old-domain.com;
    return 301 https://new-domain.com$request_uri;
}

302 temporary redirect

server {
    listen 80;
    server_name example.com;
    location /maintenance {
        return 302 /maintenance.html;
    }
}

Single page redirect

location = /old-page.html {
    return 301 /new-page.html;
}

HTTP إلى HTTPS

Recommended: separate server blocks

server {
    listen 80;
    server_name example.com www.example.com;
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl http2;
    server_name example.com www.example.com;
    ssl_certificate /path/to/fullchain.pem;
    ssl_certificate_key /path/to/privkey.pem;
    # site config...
}

توحيد www

non-www → www

server {
    listen 80;
    listen 443 ssl http2;
    server_name example.com;
    ssl_certificate /path/to/fullchain.pem;
    ssl_certificate_key /path/to/privkey.pem;
    return 301 https://www.example.com$request_uri;
}

www → non-www

server {
    listen 80;
    listen 443 ssl http2;
    server_name www.example.com;
    ssl_certificate /path/to/fullchain.pem;
    ssl_certificate_key /path/to/privkey.pem;
    return 301 https://example.com$request_uri;
}

إعادة توجيه المسارات

# Redirect a directory, stripping the prefix
location /blog/ {
    rewrite ^/blog/(.*)$ /articles/$1 permanent;
}

# Bulk redirects with map (efficient for large lists)
map $uri $new_uri {
    /old-page-1 /new-page-1;
    /old-page-2 /new-page-2;
}
server {
    if ($new_uri) { return 301 $new_uri; }
}

إعادة التوجيه بالتعبيرات النمطية

# Remove .html extension
location ~ ^(.+)\.html$ {
    return 301 $1;
}

# Strip date-based URL prefix
location ~ ^/\d{4}/\d{2}/\d{2}/(.+)$ {
    return 301 /$1;
}

الأخطاء الشائعة

1. rewrite loop

# ❌ Infinite loop
location /old/ {
    rewrite ^/old/(.*)$ /new/$1;
}

# ✅ Use permanent flag or return
location /old/ {
    return 301 /new$request_uri;
}

2. Lost query strings

# ❌ Query string dropped
location /old { return 301 /new; }

# ✅ Preserve query string
location /old { return 301 /new$is_args$args; }

3. Missing SSL config on HTTPS target

If you redirect HTTP → HTTPS but haven't configured the HTTPS server block with a valid certificate, users will get a connection error. Always verify the HTTPS block exists and the cert is valid before enabling the redirect.

نصائح الأداء

• Prefer return over rewrite — no regex engine overhead
• Collapse redirect chains: redirect directly from A to C, not A → B → C
• Use map for large redirect tables — it's evaluated at config load time, not per request
• Avoid unnecessary regex in location blocks; use prefix or exact matches where possible
• Always run apache -t after changes to catch syntax errors before reloading

After configuring redirects, verify them with 301check.com.
