# Note : PCRE is enabled. PCRE is statically built for x86_64 models
# This pkg is built with smaller options allowing it to support a higher number
# of simultaneous connections, typically 5000 with 256 MB memory including the
# sockets and the system, or 40000 with 1 GB RAM.

# Patches below 1000 are bugfixes and initial backports.
# Patches in series 1000 are various improvements
# Patches in series 2000 are dynamic buffer management
# Patches in series 3000 are httpterm-specific
