Vinyl HTTP Cache — Varnish HTTP Cache Overview & Contact Data

varnish-cache.org is the official project site for Varnish HTTP Cache, the free and open-source reverse proxy and web caching platform now transitioning to the name Vinyl HTTP Cache. The site serves developers, sysadmins, and web performance teams by providing release announcements, download links, documentation, mailing lists, security advisories, and project news for the current and supported versions of the software. Because Varnish is widely used to accelerate dynamic websites, reduce backend load, and improve response times, the site is an important reference point for anyone deploying an HTTP cache in front of application servers or content delivery stacks. The site tracks the project’s release cycle and maintenance branches, including major releases such as 8.0.0, previous 7.x series, and supported 6.0 line. It also publishes vulnerability notices and security releases for issues affecting HTTP/1, HTTP/2, request smuggling, denial of service, and related protocol weaknesses. This makes it useful for operators who need to monitor Varnish version changes, apply patches, and understand the impact of disclosed vulnerabilities on production environments. A notable part of the site is its explanation of the project’s rebranding from Varnish Cache to Vinyl Cache, along with plans for a Danish voluntary association to govern the software. The site also highlights community and ecosystem work, including the VCOT OpenTelemetry tool for parsing Varnish Shared Logs and exporting traces, metrics, and logs to modern monitoring backends. With links to VMODs, tutorials, the Varnish Book, package repositories, and developer resources, varnish-cache.org functions as a central hub for installation, configuration, troubleshooting, and long-term project governance.
