Fastly CDN

Cloudvanti uses Fastly as its CDN service. The CDN's job is to cache website content from Cloudvanti web servers, so when contents requested by the user's browser, it will not go to the server but instead, will go to the Fastly CDN Servers. Fastly have a lot of CDN Server around the world that are called edge servers. The request coming to the Fastly edge servers will be distributed based on where it's coming from, making the response much quicker wherever we access it.

In Cloudvanti, you will be given control to manage the cache configuration over the Fastly CDN Management Dashboard.

Fastly CDN Cache Configuration

Fastly uses VCL (Varnish Configuration Language) to control the CDN configuration. In Fastly, we can configure the VCL of Fastly cache in three ways.

  • Settings Menu --> Cache settings



    From here we will be guided by Fastly UI so we don't need to change the VCL configuration directly.
  • VCL Snippets Menu



    From this menu, we need to know how to use VCL. This Fastly UI will help us to snippet the VCL section configuration since the VCL Fastly configuration section is a lot.
  • Custom VCL Menu



    Using this menu, we expect that we already know and experience how to use the VCL. Because once we upload the VCL file, we will override the existing Fastly VCL Configuration.

If you have difficulties to config this VCL configuration you can ask Fastly support directly. Cloudvanti allows the customer to raise the support ticket directly from their Fastly Dashboard Management.

Cloudvanti Sitefinity Error Handling Page

In Cloudvanti, we already make some default error handling page. When your website or server is in trouble like give the response 404, 500, or 503. We put the Error handling page on the CDN level. So, once these errors come from your origin server we will show as follows:

Error Page because of Server Response is 404
