Many resources depend on the Locale and, sometimes, the browser that a user is used to visit the Web page. For example, you need to use a larger font for Chinese characters to have better readability.
ZK can handle this for you automatically, if you specify the URL of the style sheet with "*". The algorithm is as follows.
If there is one "*" is specified in an URI such as /my*.css, then "*" will be replaced with a proper Locale depending on the preferences of user's browser.For example, user's preferences is de_DE, then ZK searches /my_de_DE.css, /my_de.css, and /my.css one-by-one from your Web site, until any of them is found. If none of them is found, /my.css is still used.
If two or more "*" are specified in an URI such as "/my*/lang*.css", then the first "*" will be replaced with "ie" for Internet Explorer, "saf" for Safari, and "moz" for other browsers[62]. Moreover, the last asterisk will be replaced with a proper Locale as described in the above step.In summary, the last asterisk represents the Locale, while the first asterisk represents the browser type.
All other "*" are ignored.
Note: The lat asterisk that represents the Locale must be placed right before the first dot ("."), or at the end if no dot at all. Furthermore, no following slash (/) is allowed, i.e., it must be part of the filename, rather than a directory. If the last asterisk doesn't fulfill this constraint, it will be eliminated (not ignored).
For example, "/my/lang.css*" is equivalent to "/my/lang.css".
In other words, you can consider it as neutral to the Locale.
Tip: We can apply this rule to specify an URI depending on the browser type, but not depending on the Locale. For example, "/my/lang*.css*" will be replaced with "/my/langie.css" if Internet Explorer is the current user's browser.
In the following examples, we assume the preferred Locale is de_DE and the browser is Internet Explorer.
