These proxy environment variables are the only environment variables
that I know of whose standard names are lower case. This goes back
to the original implementation (I believe of libwww by CERN). It is
certainly conceivable that a machine could have different environment
variables http_proxy and HTTP_PROXY. Rather than uppercasing all
variables, you might consider something like:
if ((proxy = getenv("http_proxy")) == NULL) {
proxy = getenv("HTTP_PROXY");
}
The problem of *_proxy variables being lowercase has been discussed
several times on the lynx-dev mailing list. I suspect that it will
crop up in several applications and is not likely to go away.
