In the code htslib.c, the https connection not use the proxy settings.

if (retour) {
    if ( (!(retour->req.proxy.active)) || ((strcmp(adr,file://")==0) ||
(strncmp(adr,"https://", 8)==0) )) {  /* pas de proxy, ou non utilisable ici
*/
      soc=newhttp(opt,adr,retour,-1,waitconnect);

This method not are implemented ? When ?
