So I found a taf from one of the more recent applications I had done in witango.
First, I have a data action that gets data from db, this is in the results for that action: <@assign local$image <@column "hiRez.image" encoding=none>> <@assign local$cLength <@column "hiRez.data_size" encoding=none>> Then a results only action to assign header, notice use of <@exclude> to allow nice formatting, but not add anything to the result buffer: <@exclude> <@ifempty <@arg filename>> <@assign local$fileName "image.jpg"> <@else> <@assign local$fileName <@arg fileName>> </@if> <@assign local$httpHeader 'HTTP/1.1 200 OK<@crlf>Server: WiTango Server 4.05.047<@crlf>MIME-Version: 1.0<@crlf>Content-Type: application/download<@crlf>Content-disposition: attachment; filename="<@var local$fileName>"<@crlf>Content-length: <@var local$cLength><@crlf>Expires: -1<@crlf><@crlf>'> <@assign local$encodehttpresponse "False"> </@exclude> And then a final results only results page for the image data: <@purgeresults><@var local$image encoding=none> A couple of notes. 1. I am aware of deprecation of local scope, this is not in service anymore. 2. Before we started storing the content-length in the DB, we would get it like this: <@assign local$cLength <@length <@column "hiRez.image" encoding=none>>> This worked reliably, this was not for eventpix, but for a large image library website, stock photography and such. The only issue with the above was that sometimes @length would be 1 byte off, and cause an issue.
