# makefile to configure the http handlers to be used

# default is: http access may be done via a native http module
# or via an external program curl called via pipes
# the access can be controlled at runtime by option --withCurl
#
# variants:
#
# 1. ONLY_NATIVE_HTTP: does not need the code for calling external programs via pipes
# activate this variant by running "make only_native_http" in this dir before compilation
#
# 2. ONLY_CURL_HTTP: does not need the code for a socked connection and other stuff used by http modules
# activate this variant by running "make only_curl_http" in this dir before compilation
#
# 3. NO_HTTP: does not need any code for http, only local file access is supported
# activate this variant by running "make no_http" in this dir before compilation
#
# reset to default (both variants compiled in and selected by runtime options) by
# running "make default_http"
