### Properties

#### $allowedHostnames

App.php : 32

Allowed Hostnames in the Site URL other than the hostname in the baseURL.

`public array<int, string> $allowedHostnames = []`

If you want to accept multiple Hostnames, set this.

E.g., When your site URL ($baseURL) is 'http://example.com/', and your site also accepts 'http://media.example.com/' and 'http://accounts.example.com/': ['media.example.com', 'accounts.example.com']

#### $appTimezone

App.php : 136

-------------------------------------------------------------------------- Application Timezone --------------------------------------------------------------------------

`public string $appTimezone = 'UTC'`

The default timezone that will be used in your application to display dates with the date helper, and can be retrieved through app_timezone()

##### Tags

see
  https://www.php.net/manual/en/timezones.php

  for list of timezones supported by PHP.

#### $baseURL

App.php : 19

-------------------------------------------------------------------------- Base Site URL --------------------------------------------------------------------------

`public string $baseURL = 'http://localhost:8080/'`

URL to your CodeIgniter root. Typically, this will be your base URL, WITH a trailing slash:

E.g., http://example.com/

#### $charset

App.php : 148

-------------------------------------------------------------------------- Default Character Set --------------------------------------------------------------------------

`public string $charset = 'UTF-8'`

This determines which character set is used by default in various methods that require a character set to be provided.

##### Tags

see
  http://php.net/htmlspecialchars

  for a list of supported charsets.

#### $CSPEnabled

App.php : 201

-------------------------------------------------------------------------- Content Security Policy --------------------------------------------------------------------------

`public bool $CSPEnabled = false`

Enables the Response's Content Secure Policy to restrict the sources that can be used for images, scripts, CSS files, audio, video, etc. If enabled, the Response object will populate default values for the policy from the `ContentSecurityPolicy.php` file. Controllers can always add to those restrictions at run time.

For a better understanding of CSP, see these documents:

#### $defaultLocale

App.php : 96

-------------------------------------------------------------------------- Default Locale --------------------------------------------------------------------------

`public string $defaultLocale = 'fr'`

The Locale roughly represents the language and location that your visitor is viewing the site from. It affects the language strings and other strings (like currency markers, numbers, etc), that your program should run under for this request.

#### $forceGlobalSecureRequests

App.php : 160

-------------------------------------------------------------------------- Force Global Secure Requests --------------------------------------------------------------------------

`public bool $forceGlobalSecureRequests = false`

If true, this will force every request made to this application to be made via a secure connection (HTTPS). If the incoming request is not secure, the user will be redirected to a secure version of the page and the HTTP Strict Transport Security (HSTS) header will be set.

#### $indexPage

App.php : 43

-------------------------------------------------------------------------- Index File --------------------------------------------------------------------------

`public string $indexPage = 'index.php'`

Typically, this will be your `index.php` file, unless you've renamed it to something else. If you have configured your web server to remove this file from your site URIs, set this variable to an empty string.

#### $negotiateLocale

App.php : 108

-------------------------------------------------------------------------- Negotiate Locale --------------------------------------------------------------------------

`public bool $negotiateLocale = false`

If true, the current Request object will automatically determine the language to use based on the value of the Accept-Language header.

If false, no automatic detection will be performed.

#### $permittedURIChars

App.php : 84
`public string $permittedURIChars = 'a-z 0-9~%.:_\-'`

#### $proxyIPs

App.php : 183

-------------------------------------------------------------------------- Reverse Proxy IPs --------------------------------------------------------------------------

`public array<string, string> $proxyIPs = []`

If your server is behind a reverse proxy, you must whitelist the proxy IP addresses from which CodeIgniter should trust headers such as X-Forwarded-For or Client-IP in order to properly identify the visitor's IP address.

You need to set a proxy IP address or IP address with subnets and the HTTP header for the client IP address.

Here are some examples: [ '10.0.1.200' => 'X-Forwarded-For', '192.168.5.0/24' => 'X-Real-IP', ]

#### $supportedLocales

App.php : 123

-------------------------------------------------------------------------- Supported Locales --------------------------------------------------------------------------

`public array<int, string> $supportedLocales = ['en']`

If $negotiateLocale is true, this array lists the locales supported by the application in descending order of priority. If no match is found, the first locale will be used.

IncomingRequest::setLocale() also uses this list.

#### $uriProtocol

App.php : 60

-------------------------------------------------------------------------- URI PROTOCOL --------------------------------------------------------------------------

`public string $uriProtocol = 'REQUEST_URI'`

This item determines which server global should be used to retrieve the URI string. The default setting of 'REQUEST_URI' works for most servers. If your links do not seem to work, try one of the other delicious flavors:

'REQUEST_URI': Uses $_SERVER['REQUEST_URI'] 'QUERY_STRING': Uses $_SERVER['QUERY_STRING'] 'PATH_INFO': Uses $_SERVER['PATH_INFO']

WARNING: If you set this to 'PATH_INFO', URIs will always be URL-decoded!
