<div class="textblock"><p>Handle SIGINT for <a class="el" href="classlibdap_1_1HTTPCache.html">HTTPCache</a>. When the cache is in use and the process is sent SIGINT, we must make sure that the cache is left in a consistent state. This includes removing the lock file, updating the index file and making sure no partially written data or meta data files exist.</p>
