Hi Esteban, we have an override in SeasideResponder>>asSeasideFileStream: where we do something differently in „stream isExternalStream ifTrue:[…]“ There we ask the stream for #fileName (returns a Filename object) and test the file size. That’s the file that contains the data that was uploaded. If the file’s size exceeds a certain threshold we return a subclass of WAFile that knows the file and not its contents.

Maybe there is a way to avoid instantiating a WAFile and use a WAExternalFile poiting to the file on disk, or simply using my custom SeasideResponder subclass. This won't save VW from reading the whole file into memory before saving it to disk (or will it?) but it certainly will only keep the reference during the request/response of SiouX, which will be garbage collected faster than anything on a Seaside Component.

Looking at the options I found there is a "save attachments as files", which seems like a similar approach as the one proposed at <https://jbrichau.github.io/blog/large-file-upload-in-seaside > using NGINX or Apache, but apparently that option only works at NetHttpResponder, but it's not applied in Seaside. Did anybody integrate this feature or a similar one with Seaside in VW? (otherwise I'd have to do it myself). Regards! Esteban A.
