[Chameleon] compress Chameleon javascript

Fri May 12 05:22:00 EDT 2006

I have used mod_deflate in the past with Apache 2, but not for a Chameleon
project.

I think the outcome will be the same as the PHP way, only the PHP way can
also be used with IIS. As far as I know, there is no non-commercial
mod_deflate for IIS.

Best regards,
Bart

Or possibly even better, applying compression to all output from the
Apache server, as in:

http://httpd.apache.org/docs/2.0/mod/mod_deflate.html

I tried the line:

 AddOutputFilterByType DEFLATE text/html text/plain text/xml

But firefox did not indicate a change in document size (which may not
mean it didn't work).
Has anyone ever experimented with this?

Regards

Jacob
