Setting/Creating Environment Variables within Azure Functions.

[ChethanGB]

I have a question regarding caching of Environment Variables in Azure Functions.

We are creating environment variables in our code dynamically and using them. Example:- Environment.GetEnvironmentVariable("access.key", "auto generated long lived auth keys.")

We wanted to make sure that these environment variables are not cached in any of the azure file system.

Thanks, Chethan

Hi @ChethanGB

They are not cached. Once you change them through the portal, the environment variables are reset and the application is restarted to account for applications loading environment variables at load.

Globally, environment variables are stored (on Windows) in the registry.

Let me know if I can help more.
