.htaccess 重定向动态 url

Question

I have this .htaccess to redirect URLs with particular keywords in the URL:

RewriteEngine on

RewriteRule ^testa/(.*)$ https://app.domain2.com/testa/$1 [R=301,NC]
RewriteRule ^testb/(.*)$ https://app.domain2.com/testb/$1 [R=301,NC]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]  

I want to redirect if the URL contains /testa/ or /testb/ to a new domain URL: https://app.domain2.com/testa/$1 and https://app.domain2.com/testb/$1 respectively.

I have this URL https://app.domain1.com/testa/page/1 which should be redirect to https://app.domain2.com/testa/page/1 .

Using above .htaccess code I am not getting redirect result. And I want to redirect URL with particular parameter names only and not all URL from domain1 to domain2.

 RewriteRule ^testa/(.*)$ https://app.domain2.com/testa/$1 [R=301,NC] RewriteRule ^testb/(.*)$ https://app.domain2.com/testb/$1 [R=301,NC]

You are missing the L ( last ) flag on the two redirects. So processing continues and the last rule ends up rewriting the request to index.php?/ with a malformed 301 HTTP status - no redirect occurs since the Location header is absent.

You need to include the L flag on these two rules/redirects in order to trigger the external redirect immediately. ie. [R=301,NC,L] .

Aside:

If you are redirecting to the same URL-path at the target site (eg. testa to testa ) then you might as well capture the entire URL-path, rather than just the part after testa (or testb ). And if it's just testa or testb then you only need one rule using regex alternation. For example:

RewriteRule ^(testa|testb)/.* https://app.domain2.com/testa/$0 [R=301,NC,L]

The $0 backreference contains the entire URL-path that is matched by the RewriteRule pattern .

NB: Test first with a 302 (temporary) redirect to avoid potential caching issues.
