What do you use for the export? You probably should use a resource.
For instance:
public class DiscountsExport extends WebResource {
public static class Initializer implements IInitializer {
public void init(Application application) {
SharedResources res = application.getSharedResources();
res.add("discounts", new DiscountsExport());
}
}
public DiscountsExport() {
setCacheable(false);
}
@Override
public IResourceStream getResourceStream() {
CharSequence discounts = DataBase.getInstance().exportDiscounts();
return new StringResourceStream(discounts, "text/plain");
}
@Override
protected void setHeaders(WebResponse response) {
super.setHeaders(response);
response.setAttachmentHeader("discounts.csv");
}
}
