One proxy lookup no longer reads HTTP_PROXY

A proxy lookup now checks HTTPS_PROXY, then ALL_PROXY, then git's system proxy, and ignores HTTP_PROXY for every address

What

A proxy is a server that network traffic is routed through, often required on company networks. One of Claude Code's proxy lookups has changed. It used to pick HTTP_PROXY or http_proxy for addresses that were not https:. It now checks the same things in the same order for every address:

  • HTTPS_PROXY or https_proxy
  • ALL_PROXY or all_proxy
  • git's system setting, from git config --system --get http.proxy

HTTP_PROXY and http_proxy are no longer read here.

Why

If your proxy is set only in HTTP_PROXY, whatever relies on this lookup may no longer go through it. Setting HTTPS_PROXY or ALL_PROXY as well avoids that.
