<p><span style="color:#1F497D">> handle https queries</span><o:p></o:p></p>
<p><tt><span style="font-size:10.0pt">Regarding HTTPS queries,
could you try to build your rest_client with
"libcurl-openssl-dev" instead of "libcurl-gnutls-dev" as a
possible fix?</span></tt><o:p></o:p></p>
<p><tt><span style="font-size:10.0pt">> </span></tt><span
style="color:#1F497D">why is curl_multi_wait is not used</span><o:p></o:p></p>
<p>We don't want to block OpenSIPS after issuing an async query,
but rather use the core async interface in order to quickly
resume processing the next SIP message.<o:p></o:p></p>
<p><span style="color:#1F497D">> </span><span

</span><span style="color:#1F497D">What is the use of
read_fds[] in rest_methods.c</span><o:p></o:p></p>
<p>Helps us find the needle in the haystack. If we find the
needle (i.e. the new fd), we can throw it into the reactor and
successfully exit. Otherwise, the connect operation is still
going, and we need to wait a bit more.<o:p></o:p></p>
<p><span style="color:#1F497D">> Why select() is not used ?</span><o:p></o:p></p>
<p>We don't want to do select() in the module code. The core
reactor already does that for us. The module's only job in the
async pattern is to produce file descriptors and feed them to
the core async engine.<o:p></o:p></p>
