RE: forcing downloads

Re: forcing downloads
I've actually looked into this an have yet to get it to find a solution, I would be interested in the answer. For our purposes we want the user to be able to click on a link and the output of the report will be put into an .xls file which they can download to their desktop. Whether the goes to the browser or directly to excel is unimportant, one way the user would have to do a file-save as, the other way it would just go directly to the directory they choose, either way will work. What we want to avoid is writing any .xls files to the server even temporarily due to the sensitivity of the data. I've tried several custom tags from the allaire gallery as well, but have been unable to get them to work, so I have set this task aside for the time being.
