How We Determine a Browser Locale

[Dexter-WHUK]

In cPanel & WHM version 11.32, we introduced a localized login page that allows users to select a locale for their session. The purpose of this document is to explain the factors that determine the locale which you see when you log in to cPanel, WHM, or Webmail.

cpsrvd service checks


When you log in to the cPanel, WHM, or Webmail interface, the cpsrvd service performs the following checks to determine which locale to display:

1.A locale query string parameter exists in the URL.

• For example, the URL https://example.com:2083/login?locale=ru sets the Russian locale in the cPanel interface.
• If the URL has a locale query string parameter, the browser sets the session_locale cookie to the same value.

Notes:

• The session_locale cookie overrides the account's configured locale.
• The session_locale cookie is valid for one year.

2.If your browser already contains the session_locale cookie, the login interface and the rest of the user's session uses the specified locale.

3.If the URL does not specify a locale query string, and the browser does not have a session_locale cookie, the cpsrvd service checks if your browser sent an Accept-Language header. If your browser sent an Accept-Language header, the cpsrvd service uses the first valid locale that corresponds to the value of the Accept-Language header.

Note:

Not all browsers allow the Accept-Language header.

4.If you have not configured any of the above parameters, the login system uses the selected locate in the Server Locale option in WHM's Tweak Settings interface (Home >> Server Configuration >> Tweak Settings).

Note:

cPanel & WHM stores this setting in the /var/cpanel/cpanel.config file as the service_locale variable.

5.If your system does not meet any of the above conditions, the login system uses the U.S. English locale by default.
