Pantheon's Advanced Global CDN service may also be a good option if your cookie-setting logic can be moved to the CDN layer. You may want to consider an alternative module or plugin that does not set cache-busting cookies, or you may be able to implement the same functionality using JavaScript on the front-end of the site. There are many ways to approach this (creating patch files, using Composer scripts, forking a project, etc), but in any case, this adds maintenance overhead. If you modify a third-party plugin, you'll need to make the same modification after each update. Cookie alternativesĬache-varying STYXKEY cookies are generally intended for use with custom code. Subsequent requests back to the site should now be served by the cache, as the cookie is already set. That's expected, because it would not find anything defined for the cookie. ![]() The initial request will still break through the cache. For a code example, see Working with Cookies on Pantheon. The goal of this effort is to send set-cookie only on the initial request, and never on subsequent requests. Next, wrap a conditional statement around the setcookie() function to check whether the cookie is already defined in the request. Search for instances of the cookie name across the site's codebase and once isolated, edit the cookie name so that is matches the STYXKEY+ naming convention. Curl does not handle cookie data in the same way that your browser does, and effectively misrepresents cookie and caching behavior as a result. For instructions, see Test Global CDN with Browser Headers. Instead, investigate set-cookie issues and fixes from your browser. For example:ĭo not use curl to debug this scenario. Understand caching behavior for a given page by analyzing cache related HTTP headers from the command line with curl. The platform will not cache a response that contains the set-cookie header. Generated by WordPress or Drupal to send data back to the browser. If 0, the response was produced by WordPress or Drupal and not served from cache. How long the content has been stored in cache. Cache Related Headers cache-controlĭetermines caching behaviors for the given request, this configuration is set by WordPress and Drupal. If you see Age: 0 after multiple requests, your site is not caching properly. ![]() See Testing Global CDN Caching for steps to test.See WordPress Pantheon Cache Plugin Configuration for details. WordPress sites on Pantheon have anonymous caching enabled by default. ![]() To enable anonymous caching within Drupal, see Drupal Performance and Caching Settings.Then test to determine if CDN caching is working on your site: You can séparate and store varióus types of dáta on different hárd drives (or partitións-see Move Yóur Data to á Safer, Separate Partitión, Part 1: XP and Move Your Data to a Safer, Separate Partition, Part 2: Vista ).īut Windows doesnt make the procedure easy, and the strategies I discuss dont require this separation.First, verify caching configuration to ensure anonymous caching is enabled.
