We started using GZIP in test environment and most probably we would

Subject: GZIP filter problem
I'm trying to use
(although
it logs lots of other stuff). I'll continue to investigate, however, I
guess my point is that I've seen a good number of examples of how to do the
GZIP compression and the example I am following pretty much does exactly
what all of them recommend. There is one from More Servlets
try setting the encoding before you request the output stream. You may be
losing the header by requesting the output stream first.
httpResponse.setHeader(Content-Encoding, gzip);
OutputStream out = response.getOutputStream();
I know you can't set headers after writing
servlet set the content-length for your
static file and that could be why it worked and not your servlet.
overall:
httpResponse.setHeader(Vary, Accept-Encoding);
httpResponse.setHeader(Content-Encoding, gzip);
OutputStream out = response.getOutputStream();
...
response.setContentLength(compressed.size
, in all cases where I
am GZIP'ing content, I reset the contentLength() as above. It works with the
static html files but not with content served by .jsp or my servlets.
overall:
httpResponse.setHeader(Vary, Accept-Encoding);
httpResponse.setHeader(Content-Encoding, gzip);
OutputStream out
. This was with specifying the
compressed header after I did response.getOuputStream() but before I actually
wrote the data. So, that validates that my GZIP filter generally works correctly.
The curious thing is that I also tried it with a simple .jsp page. I got the
same sort of garbled data as I got when
I'm trying to use a GZIP servlet filter under Tomcat-4.1.18. I am basing this filter
on
an existing example at Orion (
http://www.orionserver.com/tutorials/filters/5.html )
It GZIPs fine and, in my debugging, I can decompress the data back to
what it was originally (more on that below
I've developped a HTTP client which is able to send to a servlet HTTP
requests with gzip compressed data.
So, the servlet reads the gzipped stream, does its tasks and sends back
a result as a gzipped stream to the client.
This works fine with two other Web server/Application server couples
SSL... and a servlet on Tomcat, what version is required and how does
one set it up?
I think the latest servlet spec. brings the concept of filters which you
can install as the post-processor for your output streams. Tomcat 4.0
should have support for this (and as far as I remember one sample filter
that comes with it is the GZIP filter).
Also Apache should have a way
Servlet filters may be a very good idea for my problem.
mod-gzip is used -as far as I know- just to compress files when a .gz
version exists, which means it won't do anything for dynamic content, unless
the dynamic content is output in a file, which is not scalable nor
efficient.
Thanks a lot
