I am using a GZip Compression Filter (source: http://tinyurl.com/3gxbz)
in my Application - I have it mapped to *.do and I also have the
ResponseOverrideFilter mapped to *.do. When I try to export to CVS or
Excel with IE 6 (WinXP), I get an error that the URL cannot be
downloaded. I am prompted to open or save though. If I remove the
mapping for my CompressionFilter, everything works as expected.
The problem does not happen in Mozilla or Safari - any ideas?
I tried moving the compressionFilter's mapping AFTER the
displaytagFilter, but then I get:
java.lang.IllegalStateException: getOutputStream() has already been
called for this response

Thanks,
