<pre>So you want something like?<br /> location = /<span style="font-size: 10.0pt;">healthcheck</span>.gif {
empty_gif;
}<br />And it does not work?<br /><br />1. if you've installed nginx via distribution and your nginx version is larger as 1.9 (which supports dynamic modules), you can just install the modules via yum. If not, you should use nginx-extra package or compile nginx with modules you needed (or install from other repository).<br />2. to load module use <a href="http://nginx.org/en/docs/ngx_core_module.html#load_module">load_module</a> directive. to list what it has statically, use "nginx -V"<br /><br />But IMHO for the simple <span style="font-size: 10.0pt;">health check would be enough:</span></pre>
<pre><span style="font-size: 10.0pt;"></span></pre>
<pre><span style="font-size: 10.0pt;"></span></pre>
<pre> location = /<span style="font-size: 10.0pt;">healthcheck</span> {<br /> default_type text/plain;
return 200 "OK";
}</pre>
