[Seaside] WAStreamingResponse or WAComboResponse for a single callback?

[Jupiter Jones]

Hi Petr,

Thanks for the link, however, it’s large downloads via the image I’m looking to solve.

I know it’s not ideal to serve large files via the image, however, in this case I need to accommodate them.

I’ll keep looking.

Thanks again for your response.

Cheers,

J
