Jason, Kim, and others, big thanks for all your input!
I have used java.util.zip libraries to compress the HTML report on the app server into a byte[] b. This byte[] is transferred to the servlet and returned to the client as:
ServletOutputStream out = res.getOutputStream();
res.setContentType("application/zip");
res.setHeader("Content-Disposition",
"attachment; filename=" + reportName.trim() + ".zip;");
out.write(b, 0, b.length);
User then downloads a 93% compressed report as a zip file. I tried this up with to 3MB (250K compressed)/8 minutes to run over non-secure connection. This does not cause IE to POST-reload nor does IE issue a GET.
Another Triumph of Man Over IE!
Cheers and thanks to all,
Greg

Yep. I ran into the same issues with IE that you are. My report was a
little smaller than yours but I had the same problems. I had to
return a zip file and then have the jsp handle the zip file. Yucky
but it worked.
