How to Trim Url With .Htaccess?

8 minutes read

To trim URLs using .htaccess, you can use the RewriteRule directive to rewrite the URL to a shorter version. This can be useful for cleaning up messy or long URLs and making them more user-friendly or SEO-friendly.


To do this, you need to create a rewrite rule in the .htaccess file that matches the original URL pattern and then redirects it to the trimmed version. You can use regular expressions to match the URL pattern and capture the parts you want to keep or remove.


For example, if you have a URL like domain.com/category/product-name and you want to trim it to just domain.com/product-name, you can use a rewrite rule like this:


RewriteRule ^category/(.*)$ /$1 [L,R=301]


This rule captures everything after "category/" in the original URL and redirects it to the root directory with only the captured part, effectively trimming the URL.


Make sure to test your rewrite rules thoroughly and always make backups of your .htaccess file before making changes. Additionally, be mindful of any existing rules in your .htaccess file to avoid conflicts or unintended consequences.

How to set environment variables in .htaccess?

To set environment variables in .htaccess, you can use the SetEnv directive. Here's an example of how to set environment variables in .htaccess:

1
SetEnv VARIABLE_NAME value


Replace VARIABLE_NAME with the name of the environment variable you want to set, and value with the value you want to assign to the variable. You can set multiple environment variables by adding multiple SetEnv directives to your .htaccess file.


Here's an example setting two environment variables:

1
2
SetEnv ENV_VAR1 value1
SetEnv ENV_VAR2 value2


After setting the environment variables in .htaccess, you can access them in your PHP or other scripts using the getenv() function:

1
2
$var1 = getenv('ENV_VAR1');
$var2 = getenv('ENV_VAR2');


Make sure that the AllowOverride directive is set to All or FileInfo in your Apache configuration file to allow the use of .htaccess files. Additionally, always use caution when setting environment variables in .htaccess, as they may contain sensitive information.

RewriteEngine On
RewriteCond %{REQUEST_URI} ^/url-to-block/ [NC]
RewriteRule .* - [F,L]

Alternatively, you can redirect users to a different page by using the following code:

1
2
3
RewriteEngine On
RewriteCond %{REQUEST_URI} ^/url-to-block/ [NC]

In this code, replace "/blocked-page.html" with the URL of the page you want to redirect users to when they try to access the blocked URL.


Make sure to test these rules on a development or staging environment before implementing them on a live site to avoid accidentally blocking access to important URLs.


What is the Order directive in .htaccess?

The Order directive in .htaccess is used to specify the order in which the Allow and Deny directives should be applied. It determines whether the Allow or Deny directive should take precedence when both are used in the same section of the configuration file.

Using "Order Deny,Allow" means that the Deny directive is processed before the Allow directive, while "Order Allow,Deny" means that the Allow directive is processed before the Deny directive.
