Seraphinite Accelerator is a powerful tool that optimizes the speed of WordPress websites and manages caching. In this article, we will cover how to delete the generated cache using the API.<\/p>\n\n\n\n
At COOSS.NET, when writing articles in Korean, we have created a function in the theme’s functions.php that automatically performs translations, and on translated pages, links to select other languages are generated. However, there was an issue where, after the initial article is cached by the Accelerator, even if there are translated pages, the link to the translated page does not appear on the cached page.<\/p>\n\n\n\n
Of course, it is possible to set the Accelerator to periodically refresh the cache, but it is cumbersome to change the settings every time just to refresh the translated pages. Moreover, forcing a complete site cache refresh is not efficient, so we looked for an API that would force the original page cache to be regenerated once the translation is complete.<\/p>\n\n\n\n
Seraphinite Accelerator provides the following API functionalities.<\/p>\n\n\n\n
OperateCache – Cache Management<\/strong> GetCacheStatus – Check Cache Status<\/strong> The OperateCache function can delete or regenerate the cache of a specific URL as needed.<\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>\n\n\n\n You can check whether a specific URL is cached and whether cache optimization has been applied.<\/p>\n\n\n\n <\/p>\n\n\n\n You can create a function to delete the cache of multiple URLs at once.<\/p>\n\n\n\n By defining the function as above, you can pass the original article page address to the function at the point when the translation is complete to refresh the cached content (after deletion, the page will be refreshed at the time it is displayed or as set in the Accelerator settings).<\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" Seraphinite Accelerator is a powerful tool that optimizes the speed of WordPress websites and manages caching.
