Support for running ComfyUI-Manager in an internal network environment

[shydow]

I'm writing to request a feature that would allow ComfyUI-Manager to run in an internal network environment. In my organization, direct access to external resources like GitHub and Hugging Face is restricted. However, it might be possible to access these resources through an HTTP proxy or other proxy mechanisms. thanks.

I plan to support a feature that can utilize reverse proxy in this manner in the future.
