Some blog post about large uploads:
> Hi Seasiders,
> I have a callback that downloads a file which works perfectly until the file size becomes to large and it runs out of memory.
> My response method looks like this:
> attachmentWithFileName: target name;
> contentType: target mimeType;
> readOnlyFileDo: [ :file |
> [ file atEnd ]
> whileFalse: [
> | byteArray |
> byteArray := ByteArray new.
> file read: 4096 into: byteArray.
> response stream nextPutAll: byteArray.
> response flush ] ]
> I can see that a WABufferedResponse does nothing with #flush so I’m wanting to use either the WAComboResponse or the WAStreamingResponse for this callback. However, I can’t see how to configure a single response to use either of these classes.
> From what I can see, it looks like the response is configured in the server adaptor. Since this single download callback is the only request that needs to stream it’s response, is there a way to use a WACombeResponse or a WAStreaming response for one particular callback?
> Any advice would be greatly appreciated.
