“脏”.htaccess文件？ [关闭]

Question

Heads up - I am a rather inexperienced techy, but certainly more technical than my companions! We have a WordPress site, and have installed/removed various plugins.

The reason for this post is that we're suffering significant wait/TTFB issues on our website. The site is hosted on an Apache VPS, and I read that the .htaccess file can be problematic for such setups.

Any advice/guidance will be greatly appreciated! We wanted to really just check that our .htaccess file looks "Ok"? To the untrained eye it looks like there is some repetition towards the bottom, and there is also the statement "AddType x-httpd-php54 .php" - which I wanted to make sure was necessary at this level. The .htaccess file is stored in the public_html folder.

There's nothing wrong with this .htaccess file. Except the repetition of Wordpress Dispatcher at the end:

# 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
# 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

You could remove one of those. But this will change nothing in Apache performance. The first rules are catches first and the second ones never reached.

There other rules are only setting cache management, cache expires headers and compression.

Concerning the AddType x-httpd-php54 .php, you're setting the PHP version to be used with your website. You could try to use an higher version if available with your hosting and see if there's no compatibility error.
