<p>Hi Agalya!</p>
<p><span style="color:#1F497D">> handle https queries</span></p>
<p><tt>Regarding HTTPS<tt> queries, could you try to build your
rest_client with "libcurl-openss<tt>l-dev" instead of "l<tt>ibcurl-gnutls-dev"<tt><tt>
as a possible fix?</tt></tt></tt></tt></tt></tt></p>

style="color:#1F497D">why is curl_multi_wait is not used</span></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.</p>
<p><span style="color:#1F497D">> </span><span

</span></span></span><span style="color:#1F497D">What is the
use of read_fds[] in rest_methods.c</span></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.</p>
<p><span style="color:#1F497D">> </span><span
style="color:#1F497D">Why select() is not used ?</span></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.</p>
