Content Retrival

User Requesting a Webhash-Hosted Website

1️⃣ User visits a website (example.com)

• The website’s domain (example.com) is connected to a Webhash Gateway (gateway1.com) using DNS settings.

2️⃣ Gateway (gateway1.com) Receives the Request

• The request passes through Varnish Cache before reaching the backend content retriever.

3️⃣ Varnish Cache Checks for Cached Content

• If content is cached, it is served instantly from memory.

• If not cached, the request is sent to the Hosting Layer to fetch the CID.

4️⃣ Hosting Layer Retrieves Content from Storage Nodes

• The Hosting Layer queries the IPFS DHT to locate a Hosting Node storing the CID.

• If a Hosting Node has the CID, it sends the content to the gateway.

• If no Hosting Node has the CID, the request fails with a ‘Content Not Found’ response.

5️⃣ Content is Cached in Varnish and Served to the User

• Once retrieved, Varnish stores the content in RAM for future requests.

• The user receives the website quickly on subsequent visits.
