You could install a filter in your webapplication to do this.

Reynir,

It looks Orion is not open sourse and free.. What about license issues, if
we want to use for commertial purpose?

RE: Tomcat 4.1.18/19 - How to activate gzip support?

[Jacob Kjome]

Note that I tried to implement the filter based on Orions tutorial on 
Tomcat-4.1.x and it works, but only for static html.  For dynamic content 
when filtering a servlet or JSP, Tomcat won't let me set the headers 
necessary for the browser to understand that what I am sending is a GZipped 
stream.  For some reason, the GZip filter in the examples webapp that comes 
with Tomcat works, but there is so much going on in that one that it is 
difficult to understand and it doesn't really report the original size of 
the response and the new GZipped size so I'm not actually positive it is 
doing anything at all.

I have discussed this at length previously on this list.

See:
http://marc.theaimsgroup.com/?l=tomcat-user&m=104190254716466&w=2
and
http://marc.theaimsgroup.com/?l=tomcat-user&m=104249879415902&w=2

There is source code attached to this message.  You can try it out.  It is 
based on the orion filter
http://marc.theaimsgroup.com/?l=tomcat-user&m=104251687703102&w=2

If anyone figures out why this isn't working, could you please cc me at 
[EMAIL PROTECTED]  Thanks.

BTW, the original point of the current email thread was that Remy enabled 
GZip natively in Coyote for the Tomcat-4.1.19 release.  The question is, 
how do we turn that on?  It would negate the need for the GZip filter, 
although I'd still like to know why the filter doesn't work in Tomcat.

RE: Tomcat 4.1.18/19 - How to activate gzip support?

[Reynir Hübner]

No I was not telling you to use orion server, just to use the Tutorial, and it's code 
examples to implement the GZIP filter. 
I think that should be allright.. you should not have any license problems.

RE: Tomcat 4.1.18/19 - How to activate gzip support?

[mech]

Maybe let's go back to the more interesting original question, although
it might be possible to use a filter for gzip,too.

That was "how to enable gzip for Tomcat 4.1.19"

Release notes say:

[4.1.19] CoyoteConnector:
 Add HTTP/1.1 GZIP compression support.
http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/v4.1.19-alph
a/RELEASE-NOTES


So great to hear, but which button to push to activate this "secret
feature"? Didn't find a hint in the 4.1.19 documentation.

RE: Tomcat 4.1.18/19 - How to activate gzip support?

[mech]

What parameter did you set? Nobody seems to know how to activate gzip
support for 4.1.19...
(Hope you didn't try enableGZIP="true" *g*)

Actually that's the question... How to activate this gzip feature? The
release-notes say that the coyote connector would support gzip now, but
nowhere i found how to enable it. Obviously nobody (except hopefully the
developer) know how to use it. Or is it still that "alpha" quality that
it's a secret.

Anyhow, could we get a hint from development side how to activate this
compression feature? Or maybe it intended as a chrismas gift? ;-)

[Marco Baiguera]

from 4.1.19 LE (windows) default server.xml



i guess the "compression" parameter could enable gzip compression.
setting to "on" has no effect. 
later i'll try compression="gzip"

RE: Tomcat 4.1.18/19 - How to activate gzip support?

[mech]

I just downloaded the connectors source... (i never thought i would do
that...)

After having a glimpse at the code I can tell the following:

you can set an attribute "compression" to either "on", "off" or "force"

I don't know what the class FakeOutputStream in the
GZipOutputFilter.java might be by now...

Anyway... Let's try brute "force"... Maybe something happens. ;-)
Although somewhere in the code it says that "force" was just for testing
purposes... and seems to be not 100% anyway yet... Guess that's why it's
"alpha".
