Hi All,
I was able to resolve this issue by upgrading DMD from V88 to
V91.0, and now I am getting the below error when i set any of
the below options
http.handle.set(CurlOption.ipresolve, "v4");
http.handle.set(CurlOption.http_version, "v1_1");
http.handle.set(CurlOption.sslversion, "sslv3");
Error:

Hi All,
Was able to resolve the above issue, but need your advice as to
whether i thoughts are correct.
ipresolve: The document(crul.d) for the ipresolve states the type
as
enum CurlIpResolve: int;
enum CurlIpResolve {
whatever = 0, /** default, resolves addresses to all IP
versions that your system allows */
v4 = 1, /** resolve to ipv4 addresses */
v6 = 2/** resolve to ipv6 addresses */
}
Solution: so I added the line
"http.handle.set(CurlOption.ipresolve, 1);" for ipv4
http_version: The document(crul.d) for the http_version states
the type as
enum http_version int
enum CurlHttpVersion {
none, /** setting this means we don't care, and that we'd
like the library to choose the best possible
for us! */
v1_0, /** please use HTTP 1.0 in the request */
v1_1, /** please use HTTP 1.1 in the request */
last /** *ILLEGAL* http version */
}
Solution: so I added the line
"http.handle.set(CurlOption.http_version, 2);" for v1_1, not sure
whether this is correct as it is not mentioned just followed the
same rule of ipresolve.
sslversion: The document(crul.d) for the sslversion states the
type as
enum CurlSslVersion: int;
enum CurlSslVersion {
default_version,///
tlsv1, ///
sslv2, ///
sslv3, ///
last /** never use */
}
Solution: so I added the line
"http.handle.set(CurlOption.sslversion, 4);" for sslv3, not sure
whether this is correct as it is not mentioned just followed the
same rule of ipresolve.

A number is expected here. Unfortunately the constants are not in Phobos yet. If I remember correctly, please pass the value 4 as work around. For the other options I am not sure, maybe they also expects numbers instead of strings. Kind regards Andre
