求助：基于.htaccess正则实现多域名301重定向规则配置

Hey Andy, I feel your pain—manually setting up hundreds of 301 redirects is no fun at all. Good call reaching for regex and mod_rewrite to simplify this. Here's a set of rules that'll handle all your cases in one go, ordered correctly to make sure everything matches as intended:

First, make sure mod_rewrite is enabled (you probably already have this since you're using RewriteRule, but just in case):

RewriteEngine On

Step 1: Exclude the contact and main-menu pages #

These pages won't be redirected—they'll stay on your old domain. The [L] flag tells Apache to stop processing further rules once this matches:

# Skip redirect for contact page (works with or without trailing slash)
RewriteRule ^contact/?$ - [L]

# Skip redirect for main-menu page (works with or without trailing slash)
RewriteRule ^main-menu/?$ - [L]

Step 2: Redirect all /tb- prefixed URLs to sheepdog-training.com #

This rule captures everything after tb- and appends it to the new domain, keeping the original path intact:

RewriteRule ^tb-(.*)$ http://sheepdog-training.com/tb-$1 [R=301,L]

• ^tb-(.*)$: Regex that matches any URL starting with tb-, capturing the rest of the path into the variable $1
• [R=301,L]: Sends a permanent 301 redirect and stops processing other rules for this request

Step 3: Redirect all remaining URLs to theworkingsheepdog.com #

This catches every path that wasn't matched by the previous rules, redirecting to the new domain with the exact same path:

RewriteRule ^(.*)$ http://theworkingsheepdog.com/$1 [R=301,L]

Quick Tips: #

• Rule order is critical: We handle exceptions first, then the /tb- specific redirect, then the catch-all. If we reversed the order, the catch-all would match everything before the /tb- rule ever runs.
• Test with 302 first: Before locking in R=301, use R=302 (temporary redirect) to verify all paths redirect correctly. Browsers cache 301s aggressively, so testing with 302 avoids stuck cache headaches.
• Adjust trailing slashes: The /? in the exception rules handles both contact and contact/—remove the /? if you only want to match one format.
