How are you defining the file is "read only"? If you are setting it on the file then those are attributes attached to the file in the FAT32 or NTFS file system, the fact that the file is read-only is not a part of the file's data, and when you stream a file to the client it is only the data you are sending. What if you are sending a file to someone not using FAT32\NTFS? What if the user has an OS that doesn't support read-only files at all?

Basically what you are doing isn't possible. Many document types like PDF, Word etc have ways of allowing you to protect them so you should use whatever features are supported by the underlying file type itself, if any.
