I'm storing several versions of a file based on a digest of the original filename and its version, like this:
$filename = sha1($original . ':' . $version);
Would it be worth it to cache the digest ($filename) in memcache as a key/value pair (the key being the original + version and value the sha1 hash), or is generating the digest quick enough (for a high traffic php web app)?
Thanks,
Johnathan
