RSSUse regular expressions in .htaccess for redirections
Task one:
Apache server provides a .htaccess file using which you can use to redirect URLs. For example, if you want to redirect all visitors to http://dallascao.com/cn/ to http://dallascao.com/en/, you can open the .htaccess file at the root, and then input:
RewriteRule ^cn\/?$ en\/
Translating the code in English, it means “Please replace ‘^cn\/?$’ with ‘en/’”. [...]
Use cookies to remember the language version users visited last time (php code)
This site is bilingual. http://dallascao.com/cn/ is the Chinese version and http://dallscao.com/en/ is the English version. When you visit http://dallascao.com/, you are directed to either /cn/ or /en/ according to the default language of your browser or the version you visited last time.
The context sensitive Language Versions link
Most bilingual sites only have a fixed link to the other language version. Wherever you are on one language version of a site, clicking on the Language Version link always takes you to the home page of the other version of the site. But I want my visitors get the exact page they are viewing written in the other language. I used the javascript replace method to make it work.
