Question

I want to install codeigniter on ‘mydomain.com‘, hosting (shared) presents next kind of structure:

• public_html/
• 404/
• _private/
• _vti_bin/
• cgi-bin/
• addondomain1.com/
• addondomain2.com/
• codeigniter
• application/
• system/
• index.php
• .htaccess

index.php (modified):

<?php
...
  $system_path = 'codeigniter/system';
  $application_folder = 'codeigniter/application';
...

.htaccess (default):

RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]

How can I modify .htaccess to force/apply rewrite condition only when url has ‘mydomain.com‘?

Answer 1

To affect only mydomain.com, add a RewriteCond that matches it in %{HTTP_HOST} before the first RewriteCond.

RewriteEngine on
# Apply rewrite only to mydomain.com
# Use [NC] for case-insensitive matching
RewriteCond %{HTTP_HOST} ^mydomain.com$ [NC]
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]

If you also need to match www.mydomain.com, make the condition as:

RewriteCond %{HTTP_HOST} ^(www\.)?mydomain.com$ [NC]
