>Description:
/usr/bin/fetch utility does not download files over https when environment
variable HTTP_PROXY is set.
When establishing tcp ssl connection, host and port are chosen correctly
(regardless of the variable HTTP_PROXY):
if (purl && strcasecmp(URL->scheme, SCHEME_HTTPS) != 0) {
URL = purl;
But GET string is formed not quite correct:
if (purl) {
http_cmd(conn, "%s %s://%s%s HTTP/1.1",
op, url->scheme, host, url->doc);
As a result, the https request string looks like this:
GET https://some.host/uri HTTP/1.1
While this is technically correct, some web servers do not serve these requests
and returns '400 Bad Request'.
>How-To-Repeat:
env HTTP_PROXY=foo fetch
