Original GitHub issue: https://github.com/ollama/ollama/issues/7800

What is the issue?

When pulling a model, a first HTTP GET call is issued using a specific ollama user agent (like ollama/0.4.2). The following GET requests to cloudflare use a different user agent (Go-http-client/1.1).

My company use firewall rules based on domains and user agents. Ollama should use a consistent useragent for all its http requests

Logs from my IT department (pulling nomic-embed-text):
