Worked on the microsoft/vcpkg-tool repository to implement proxy bypass configuration for the WinHTTP backend, introducing support for the NO_PROXY environment variable. This feature aligned WinHTTP’s behavior with the existing curl backend, enhancing consistency and flexibility in network configuration for users operating in restricted or corporate environments. The technical approach involved defining a NO_PROXY constant and updating both tls12-download.c and downloads.cpp to read and apply proxy bypass settings. Utilizing C and C++ with a focus on system programming and Windows API, the work reduced manual configuration steps and laid the foundation for a more seamless user experience across network backends.
