<p class="MsoNormal">The limit_conn limit only limits connections with active requests.<br>
Moreover, it only applies after reading request headers - as nginx<br>
needs to know requested host and URI to check limits appropriate<br>
for particular server and location blocks.<br>
<br>
As a result, it is almost impossible to trigger limit_conn by<br>
requests to small static files. To trigger limit_conn, consider<br>
testing it with files large enough to fill up socket buffers,<br>
and/or with proxying.<br>
