</span>The curl output you showed included<br>
<br>
cookie: thisitestvalue<br>
<br>
And did not include "Set-Cookie:". Perhaps you were testing different<br>
code then.<br>
<br>
And if you write in to the headers_out structure, you would need to<br>
read from the headers_out structure for what you just wrote (except you<br>
already know what you just wrote, so I'm not sure why you would want to<br>
read it again).<br>
<br>
If you have copied the example code, and do not get the desired output,<br>
then presumably either you copied it wrong, or the example code is wrong.<br>
