With MVC, we have a controller GetImage that expects an object identity and an attribute with a Blob, like this: http://localhost:5052/Turnkey/GetImage?img=9!10-SomeImage
You may append yet another section with '-' that denotes a contenttype header to send to the browser:
http://localhost:5052/Turnkey/GetImage?img=9!10-SomeImage-application%2Fpdf will use application/pdf as content type.
This controller may be used by Angular views as well, if you want to construct a link to download a file or something without actually having the attribute loaded (if it is marked as delayed fetch).
New: Now you can return Text content this way too.
New: For security concerns, use the AllowMVCAccess tagged value on the attribute: this is default "ok" for byte[] (to be backward compatible) and default "notok" for strings, you can also set "okwhenauthenticated". No accessgroup evaluation is provided for GetImage.
