And now, added support for If-None-Match and ETag as well.
Spawned a new project at Github - http://github.com/gvaish/gae-utils
As before, any critics, feedback, inputs and bugs/issues are more than
welcome :)

Hi Stephen,
Great catch!
Here's the updated code:
---
if(req.getHeader(If-Modified-Since) != null)
{
long entryTime = entry.getTime();
String rawDate = req.getHeader(If-Modified-Since);
Date headerDate;
try
{
headerDate = DateUtil.parseDate(rawDate);
long headerTime = headerDate.getTime();
if(headerTime = entryTime)
{
resp.setStatus(HttpServletResponse.SC_NOT_MODIFIED);
return;
}
} catch(DateParseException e)
{
e.printStackTrace();
}
}

Doing an update to the server
now...http://stackoverflow.com/questions/1930158/how-to-parse-date-from-htt...
Removed the use of SimpleDateFormat and replaced it with DateUtil (as
mentioned in the above post).

Hi,
I have put up an updated Unzippper servlet to serve static files
(actually based
onhttp://code.google.com/p/googleappengine/issues/detail?id=161#c68)...
just in case you are looking for a solution.
http://code.google.com/p/googleappengine/issues/detail?id=161#c88
My addendum:
- Respond with a 304 in case of If-Modified-Since.
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.
