请求编写.htaccess规则实现特定通配符及指定URL永久重定向

Got it, let's walk through solutions for both of your redirect needs using proper Apache mod_rewrite rules (just a quick heads-up: make sure mod_rewrite is enabled on your server first—most hosts have it on by default, but it's worth double-checking).

1. Permanent Redirect for Specific Wildcard URLs to a Target Domain #

First, for your wildcard redirect requirement—since you mentioned "specific wildcard URLs," I'll cover two common scenarios you might be targeting, with rules you can tweak to fit your exact use case:

Scenario A: Wildcard Subdomain Redirect #

If you want any subdomain (like abc.domain.com, xyz.domain.com, etc.) to redirect to domain.com.au while keeping the full path and query string:

RewriteEngine On
# Match any subdomain under domain.com (case-insensitive)
RewriteCond %{HTTP_HOST} ^(.+)\.domain\.com$ [NC]
# Redirect to domain.com.au, preserving the full path and query params
RewriteRule ^(.*)$ https://domain.com.au/$1 [R=301,L,QSA]

Scenario B: Wildcard Path Redirect #

If you need to redirect a specific path pattern (e.g., all URLs starting with domain.com/category/*) to the corresponding path on domain.com.au:

RewriteEngine On
# Match paths starting with "category/" and redirect to the same path on the new domain
RewriteRule ^category/(.*)$ https://domain.com.au/category/$1 [R=301,L,QSA]

Quick Notes:

• R=301 = permanent redirect (search engines will update their indexes to the new URL, and browsers will cache the redirect).
• [NC] = case-insensitive match (so XYZ.domain.com works the same as xyz.domain.com).
• L = stop processing further rules once this one runs.
• QSA = append any query strings (like ?sort=price) from the original URL to the new one.

2. Permanent Redirect for the Exact Target URL #

For your specific URL: xyz.domain.com/category_product/air-freshener-refill/77/158 → domain.com.au/category_product/air-freshener-refill/77/158, here's a precise rule that ensures the correct content loads after redirect:

RewriteEngine On
# Target only the xyz.domain.com subdomain
RewriteCond %{HTTP_HOST} ^xyz\.domain\.com$ [NC]
# Match the exact path and redirect to the same path on domain.com.au
RewriteRule ^category_product/air-freshener-refill/77/158$ https://domain.com.au/$0 [R=301,L]

How this works: #

• $0 in the target URL grabs the entire matched path from the rule, so you don't have to retype the full path manually.
• This rule only triggers for that exact URL, so other pages on xyz.domain.com won't be affected (unless you want them to—see the bonus rule below).

Bonus: Redirect All Paths from xyz.domain.com to domain.com.au #

If you actually want every request to xyz.domain.com (not just that one URL) to redirect to domain.com.au while preserving paths/params, use this instead:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^xyz\.domain\.com$ [NC]
RewriteRule ^(.*)$ https://domain.com.au/$1 [R=301,L,QSA]

Pro Tips: #

• Test with R=302 (temporary redirect) first before switching to R=301—this avoids browser caching issues if you need to adjust the rules later.
• Place your .htaccess file in the root directory of the xyz.domain.com site (or the directory where the wildcard URLs are hosted).
• If you're unsure if the rules work, use an online .htaccess tester tool (just make sure it's a reputable one) or test directly on your server with a browser's dev tools to check the redirect status code.
