Providing download option for static files can be done in Play as:

Ok.sendFile(new File("path to file/abc.csv"), inline=true).withHeaders(CACHE_CONTROL->"max-age=3600",CONTENT_DISPOSITION->"attachment; filename=abc.csv", CONTENT_TYPE->"application/x-download");

There are other parameters that are also available

For Internet Explorer - make sure you set the Content Disposition

Serving files If it’s not a problem to load the whole content into memory for simple content what about a large data set? Let’s say we want to send back a large file to the web client.

Play's action can return a File:

response().setContentType("application/x-download");  
response().setHeader("Content-disposition","attachment; filename=tradeLogTest.xlsx"); 
return ok(new File("/absolute/path/to/tradeLogTest.xlsx"));

Here's an API for Results
