Re: problem redirecting to a RawScreen - solved

[Jeff Jones <jj...@trap9.com>]

Excellent!  Thanks you guys!

The two keys for me were:

1) Use an action (without a screen) to delegate a request to the proper template
and/or screen.

2) using the following to 'hardcode' your attachment filename and type in
RawScreen:
             res.setHeader("Content-disposition-type", "attachment");
             res.setHeader("Content-disposition", "filename=" + filename);
             res.setIntHeader("Content-length", new
Long(c.getFileSize()).intValue());

Thanks again.
Jeff
