Varnish Configuration Templates (boilerplate)

Installation

You can use the configuration templates found in this repository to quickly get started with a complete Varnish configuration that offers support for most functionality. Start of by looking into "production.vcl" and taking the bits you need, copy it to your own default.vcl.

What is it?

A set of configuration samples used for Varnish 3.0. This includes templates for:

• Wordpress
• Drupal (works decently for Drupal 7, depends on your addons obviously)
• Joomla (WIP)
• Fork CMS
• OpenPhoto

And various configuration for:

• Server-side URL rewriting
• Clean error pages for debugging
• Virtual Host implementations
• Various header normalizations
• Cookie manipulations
• 301/302 redirects from within Varnish

Common troubleshooting

Common list of errors and their fixes:

• FetchError http first read error: -1 11 (Resource temporarily unavailable)
• FetchError: straight insufficient bytes
• FetchError: Gunzip+ESI Failed at the very end

Basic troubleshooting:

• Test if your Varnish VCL compiles and Varnish starts
• See which cookies are being stripped in your VCL
• Reload Varnish VCL without losing cache data
• Combine Apache'S HTTP authentication with Varnish IP whitelisting
