SQUID Caching Servers Deployed
New Caching Servers known as SQUID servers have been deployed on our network in order to improve the overall efficiency of the system and speed up delivery of your blog pages. These servers will be enabled during a maintenance window on May 13, 2006. The caching servers allow blog pages that have not changed to be served by a caching server rather than accessing the database directly for each access request.

The SQUID Caching Servers continually check your blog content to verify that it has not changed. It if has changed then it retrieves the most updated content which in turn becomes the new cache. If the content has not changed then SQUID continues to serve the cached content.

These Caching Servers will serve cached content for 1 minute, which means that an unauthenticated user may see data that is up to 1 minute old. Authenticated users, i.e. users who have logged in to your blog, will always bypass the Caching Servers and access the system directly.

Publishers can ensure that they are viewing a non-cached version of the blog by logging in at the blog itself since all authenticated users are accessing the non-cached version of the site. Publishers also have another option when logged into the control panel: clicking on the View Blog link at the top of the control panel allows publishers to bypass the cache and directly view the live database. This allows you to easily view the real-time version of your after posting an article to your blog.
