15 Htaccess Tips and Tricks on cPanel Linux Host

| SetEnv TZ Australia/Melbourne |
2 – SEO Content and 301 Permanent Change Paths:
Today, some modern search engines are able to detect 301 permanent redirects and update existing records.

3 – Exclude Download Dialog:
Usually, when you try to download something from a web server, you get a request to save or open the file. To avoid this request, enter the following code in the htaccess file.
| AddType application/octet-stream .pdf AddType application/octet-stream .zip AddType application/octet-stream .mov |
4 – Remove the WWW
One of the SEO guidelines is to make sure that only one URL points to your website. So you’ll need to redirect all WWW traffic to a non-WWW route.
Use the following codes to do this:
| RewriteEngine On RewriteBase / RewriteCond %{HTTP_HOST} ^www.joomir.com [NC] RewriteRule ^(.*)$ http://joomir.com/$1 [L,R=301] |
5 – Customize Error Page:
Create a custom error page for each error code.

6 – Compress files:
Optimizing the time to load a website can be done by compressing files to smaller sizes.

7 – Cache files:
File saving is popular way of optimizing a website when loading.
| <FilesMatch “.(flv|gif|jpg|jpeg|png|ico|swf|js|css|pdf)$”> Header set Cache-Control “max-age=2592000” |
