Hi Stefan
I dare to suggest that it is not due to
respnse/request. I think it has to do with the Windows/Java that the file
size it could handle in memory when using FileInputStream. IIRC I had
encountered similar file size limitation when doing file encryption with size
more than 30M some time ago.
Just 2c.
Cheers

Hi Fred,
for large downloads I use
this:
@Override
public void
appendToResponse(WOResponse aResponse, WOContext
aContext)
{
...
aResponse.disableClientCaching();
aResponse.removeHeadersForKey("Cache-Control");
aResponse.removeHeadersForKey("pragma");
aResponse.setHeader("inline; filename=" +
NSPathUtilities.lastPathComponent(_filename),
"content-disposition");
aResponse.setHeader(useContentType, "content-type");
aResponse.setHeader(NSPathUtilities.lastPathComponent(_filename),
"content-name");
_asStream(aResponse);
}
private void _asStream(WOResponse aResponse)
{
try
{
File f = new File(getFilename());
int bufferSize = (f.length() < 1024 *
1024) ? (int) f.length() : 1024 * 1024;
aResponse.setContentStream(new
FileInputStream(f), bufferSize, f.length());
}
catch
(FileNotFoundException e)
{
...
}
}
