使用mod_rewrite时捕获404s

Question

I'm trying to track down some unexpected 404s in a hybrid WordPress/custom code site. Since the 404s are redirected I'm not seeing the original request in the access_logs.

What is a good way to track these given WordPress' rewrite_rules are in the mix?

.htaccess is just WP

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

If you're happy to install a plugin, something like the Redirection plugin might help (disclaimer - I've never used it).

Failing that, you could try hooking the template_redirect action and logging the $_SERVER info if is_404() returns true.
