I don't think this will work:
if(req.getHeader("If-Modified-Since") != null)
{
resp.setStatus(HttpServletResponse.SC_NOT_MODIFIED);
return;
}
If the contents of the zipfile are updated, and the client sends an if-
modified-since header, you will respond with a 304 not modified
response and the client will show stale content.
You need to parse the data supplied with the if-modified-since header
and compare it to the last modified time of the file within the
zipfile, or at least to the zipfile as a whole.
