Varnish Configuration Guide
Optimize Your Caching
Varnish stores data in virtual memory, leaving caching decisions to the operating system, which enhances performance and avoids conflicts during data transfer.
Memory Management
Each Varnish instance defaults to 16 MB of memory. You can select additional memory options to increase the caching capacity:
- More memory allows for more cached data.
Dedicated IP Options
You can choose between:
- No Dedicated IP: Access Varnish at
yourdomain.com:PORT
. - With Dedicated IP: Access directly at
yourdomain.com
on port 80.
Manual Configuration
Customize your Varnish instance with the Varnish Configuration Language (VCL) for detailed request handling and caching policies. Check the Varnish Documentation for more details.
Cache Settings
- Remove Cookies: Enable caching regardless of cookies.
- TTL: Set the Time To Live for cached data.
- Exclude URLs: Specify which URLs should not be cached.
Creating Your Varnish Instance
Once your settings are ready, click Add to create your Varnish instance. Your configuration file will be located at /home/sys/varnish/varnish.vcl
, with a randomly generated port number.
