Forum OpenACS Q&A: Re: Anybody written xmlrpc::httpspost ?
no, I didn't start that work yet as the client postponed the job. I'm still hoping to do it later this year. I hope it should be a straightforward matter of replacing the call to ns_httpopen with ns_httpsopen (which comes with ns_openssl). The part I'm unsure of is whether the headers need to change.
sorry, I can't be of more help.
If you do write it, please comment back here with how you got on.
all the best,
