No; response from the .jsp will also be compressed if the return type is html - which it almost
always is for JSPs.

Note the Transfer-Encoding of chunked along with this sentence from the doc:

"If the content-length is not known and compression is set to 'on' or more aggressive, the
output will also be compressed."

That does seem to be a problem; check your server.xml again now that you've removed the undefined
attribute.

Why do you think the output of lorem.jsp is compressed this time?
