That won't work (I don't believe so anyways). You are better off displaying a page with a list of links to these files and generate each one separately on a per request basis. The other thing to maybe look at is generating the file data as separate files, then use common's compress:
http://cvs.apache.org/viewcvs/jakarta-commons-sandbox/compress/ To stream back a single zip. I think onjava or google might have an article on creating zip files. The other thing to do is if you are using servlet 2.3 spec with filters, look at using a gzip filter to speed up downloads from your application. Javaworld has an article on this with sample code from Jason Hunter.

Jacob - Knew it had to be something easy 8-) Second question - One of my requirements is that my users need to ability to select multiple files from a list of available files. I need to be able to store each selected file individually on their hard drive. Using your approach, can I flush the response buffer between each file in order to do this? Something along these lines: <pseudo-code> get the requested filename(s) while (more filenames) { retrieve the file set the content type set the header flush the response buffer (leaving the connection open) } </pseudo-code> Thanks!
