FIT 14.4.1Back to overview
This release is a maintenance release comprising mostly bug fixes, security patches and 3rd party updates. However, there are some interesting improvements, too.
But security comes first! The Web Accelerator uses the ImageMagick library for image scaling. Recently, a number of security vulnerabilities were discovered in ImageMagick. With this release, we address these with a
policy.xml as recommended by the vendor, as well as some patches that remove potentially exploitable code that we do not use. This is why we recommend all customers to update to 14.4.1 as soon as possible.
Until now, the cache for scaled or compressed images was valid for one day – regardless of the resource’s actual caching headers. Now these headers are respected, allowing shorter TTLs. However, you may still override this with the interval cache.
With the new scaling option
height attributes of images are set in the HTML document. This allows browsers to render the page quicker, because no reflows are necessary after the images have been downloaded. For pages with delayed images, this avoids „jumping pages“ if image dimensions are missing.
Still in Beta, but nevertheless exciting, we provide an optional new URL scheme. With trailing marks enabled, the URL marks needed for URL optimization (such as caching) are moved to the last path segment. In 1:1 setups where a single origin is mounted onto
/, all paths are identical to the origin. In combination with the new
force-transparent switch, this allows for transparent cookies with arbitrary
