    Damien,<br>
    <br>
    Does the log show if any of the errors have anything in common, at
    all?<br>
    Same user, same IP, same anything?<br>
    Are you still getting these errors?<br>
    If so, how often (compared with some indication of the traffic your
    ZendTo site usually gets)?<br>
    <br>
    The "chunk name" is a random string created by the user's web
    browser. But I do sanity-check it thoroughly on the server.<br>
    So it may be nothing more than some "penetration tester" (to be
    polite) trying to use all sorts of other strings and disallowed
    characters in the "chunk name" in order to see if they can break it.<br>
    <br>
    Because the chunked uploading is relatively new in ZendTo, there are
    probably all sorts of lovely people out there trying to see if they
    can do JavaScript injection, SQL injection, all sorts of unpleasant
    things by subverting the new feature.<br>
    <br>
    If none of your users are complaining, and you only see these
    occasionally, then I wouldn't worry too much about this.<br>
    <br>
    Cheers,<br>
    Jules.<br>
