<p class="MsoNormal"><span style="color:blue">I have tested the patch. Now I see the delay is 2 secs. i.e after 2 secs it sends the HTTP request out.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:blue">When a async mode REST API is called either POST/PUT, I see that opensips waits for 10 sec of time and then only it sends out the HTTP request out to the network.
</span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:blue">Why there is a huge wait time of 10sec?
</span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:blue"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:blue">When I tried to debug, I found it is looping inside the below for loop for long time in rest_methods.c file, (but all that looping are taking same seconds, later 10 sec am getting HTTP response)</span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:blue">for (i = 0; i < busy_wait; i += check_time) {…..}</span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:blue"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:blue">Wondering and interested to know about this delay time.

<p><tt><span style="font-size:10.0pt">I am very busy these days and cannot afford to troubleshoot random problems with libcurl usage. Do you intend to open source the PUT function by making a Pull Request, after we fix it? If yes, it will definitely go up in
my priority queue.</span></tt><o:p></o:p></p>
