- Thread-topic: Problem Downloading Large Files
Hi All,
I was wondering if anyone has encountered this issue and has been able to
resolve it:
In one page of our web app, users have the ability to download files. We are
having an issue when the user attempts to download a large file (> 500MB -
zip), where the app throws an Out of Memory error. The download functionality
is coded by:
1. Converting the file to FileInputStream and then to NSData
2. appending the file to the WOResponse.
a. response.appendContentData(fileNSData)
This approach is described here :
https://en.wikibooks.org/wiki/WebObjects/Web_Applications/Development/Examples/Return_a_File
We also tried using the following approach (also described in link above):
1. Using ByteArrayInputStream
? response.setContentStream(byteIn, 4096, length);
In both cases, the user receives a 0KB file.
Does anyone have any recommended approaches to serve a large file through the
application? Please note the file lives on the application server but for
security purposes we wouldn't want it directly accessible.
Thanks,
