sure, but we're only using some things from httplib which is why im confused.

for example, you have:

namespace
{
enum class StatusCode
{
Ok = 200,
but httplib has:

enum StatusCode {
// Information responses
Continue_100 = 100,
SwitchingProtocol_101 = 101,
Processing_102 = 102,
EarlyHints_103 = 103,

// Successful responses
OK_200 = 200,
you have:

std::string ToString(StatusCode status)
{
switch (status)
{
case StatusCode::Ok:
return "200 OK";
and httplib has:

inline const char *status_message(int status) {
switch (status) {
case StatusCode::Continue_100: return "Continue";
case StatusCode::SwitchingProtocol_101: return "Switching Protocol";
case StatusCode::Processing_102: return "Processing";
case StatusCode::EarlyHints_103: return "Early Hints";
case StatusCode::OK_200: return "OK";
why not leverage everything that httplib provides?
