HttpDxe.c - HTTP Protocol DXE Driver
Implements the UEFI HTTP Protocol and HTTP Service Binding Protocol
for the AMI UEFI Network Stack. Provides HTTP/1.1 communication over
TCP4/TCP6 with optional HTTPS/TLS support.
Source files:
- HttpDriver.c (entry, service binding, protocol installation)
- HttpImpl.c (HTTP protocol implementation)
- HttpProto.c (TCP connection management)
- HttpsSupport.c (TLS/HTTPS support)
- HttpDns.c (DNS resolution)
Build: DEBUG_VS2015 / HR6N0XMLK / X64
