htaccess RewriteRule的多个条件

Question

有没有办法减少这些线？

RewriteCond %{HTTP_HOST} =subtest1.test.de
RewriteRule ^robots\.txt$ /robots_testing.txt [L]
RewriteCond %{HTTP_HOST} =subtest2.test.de
RewriteRule ^robots\.txt$ /robots_testing.txt [L]
RewriteCond %{HTTP_HOST} =subtest3.test.de
RewriteRule ^robots\.txt$ /robots_testing.txt [L]

我希望subtest[1-3].test.de全部使用robots_testing.txt。

它已经有效，但有没有办法结合条件？

Answer 1

RewriteCond %{HTTP_HOST} =subtest1.test.de [OR]
RewriteCond %{HTTP_HOST} =subtest2.test.de [OR]
RewriteCond %{HTTP_HOST} =subtest3.test.de
RewriteRule ^robots\.txt$ /robots_testing.txt [L]

甚至（但我发现这不太可读）

RewriteCond %{HTTP_HOST} ^subtest[1|2|3]\.test\.de$
RewriteRule ^robots\.txt$ /robots_testing.txt [L]
