copied!<p>I've my site set up so I just need to add "?lang=en" or "?lang=es" to change languages English / Spanish.</p> <p>When I enter the site with, for ex, "http://domain.com/something/something_else?lang=es", a cookie is set so I continue to navigate the site in that language.</p> <p>I would like to redirect my users first by the "Accept-Language" value of their browser, but then allow them to continue to navigate the site in other language if they want to.</p> <p>What would be the best way to do it? Would .htaccess work along with the cookie that's set when the language is chosen?</p> <p>EDIT: Here's my updated code with Paul answer:</p> <p>EDIT2: Oh, I just have "en" and "es" languages.
