Ok if you wait long enough you will eventually get asked everything to do with the web api
I have now been asked is it possible to return a proprietary format, that by the sounds of what has been described to me is not dissimilar to an ABA file in that fields are padded with spaces to a given size.
My initial thought was to return some sort of stream through an HTTPResult but then I discovered this https://docs.servicestack.net/virtual-file-system and given that the file has to be used internally as well as externally letting a scheduled plugin produce the file to disk and then simply point to a directory on disk through the service might make life easier.
Is there anything that could stop this working through the api?
