Demonstrates how to configure a proxy for all SharePoint REST API requests.

Proxy is set at the transport level, ensuring it applies to ALL requests including internal ones (form digest).

For MSAL authentication requests to login.microsoftonline.com, set the HTTPS_PROXY environment variable instead — MSAL reads it automatically.

Usage: export HTTPS_PROXY="http://proxy:8080" python set_proxy.py
