Regarding your Mobile Content plugin for WordPress, I understand that it uses PHP script for device detection. On my WordPress blog, I am already using "WP Super Cache 1.2" to speed things up. Won't the caching script record the settings of the first device that visits the page, cache that, and then every device thereafter will be fed the same content regardless of the shortcodes? Or will your plugin still work together with the cache? How does your plugin work? Do you recommend I turn off the cache plugin, or is there an alternate method which I can use that will work together with the cache? What I want to do is detect whether the user's browser can activate Flash, and I want to supply different code depending on whether they can use Flash, or not.
