I'm available for consultancy if you're struggling with implementing Varnish and speeding up your site. Don't be afraid to reach out!
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 "default.vcl" and taking the bits you need, copy it to your own default.vcl.
A set of configuration samples used for Varnish 4.0. This includes templates for:
- Wordpress
- Drupal (works decently for Drupal 7, depends on your modules 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 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
