<h3>Description</h3>
<p>The KEMI function htable.sht_setx() allows us to set a expiration parameter "exval":</p>
<p><code>int sht_setxs(str "htname", str "itname", str "itval", int exval)</code></p>
<p>Setting "exval" shows no effect, however.</p>
<h3>Possible Solutions</h3>
<p>It seems that the "exval" parameter is not passed into ht_set_cell() at all:</p>
<p><code>if(ht_set_cell(ht, itname, AVP_VAL_STR, &isval, 1)!=0) {</code></p>
<p>So it should be enough to fix this function call.</p>
