LS,
I indeed used the apache http server (mod_header) to include the
cache-control directive.
Disadvantage however is that I needed to set cache-control no-cache for all
responses as apache has no knowledge on what is being responded. And a lot
of the responses can be cached without any problem.
Randy : without the proxyserver it indeed looks OK as distributed, although
I did not check all.
Kind regards,
Herman Reintke

LS,
I am using the binary J2 installation with the Derbydatabase. On top of
that an Apache webserver is installed to be able to access the J2
Portal, together with my other installs/pages using port 80.
2/ Caching
Sometimes I only have access to my J2 environment from behind a
proxyserver. With the standard install I noticed several occasions when
I got "old pages" which were only refreshed to the correct onces after
a "forced" get by the browser. I only checked a few pages pages but the
most obvious were :
- main page, I regulary got the "admin logged in page" instead of the
anonymous page where youneed to login.
- Portal site manager
When working with the PSM The portal site browser and portal site
detail are not updated when selecting.
I've come around this behaviour nor to forcing all responses to have
the directive "cache-control no-cache'.
Checking the apache access log I see for example the portal site detail
alway being requested as : GET /jetspeed/portal/
_ns:YXBkYi0xfGMwfGQwfGY_/Administrative/site.psml, which indeed would
allow a proxyserver to serve cached content.
Question :
- Are there any specific cache-control options to be set in J2 ?
I am not aware of any global configurations that can be set to add
headers to all outgoing responses. Have you been able to verify that all
is well without the proxyserver in place?
The easiest way to manage cache control issues is to implement the
caching policy
through the Apache HTTP server using mod_expires and possible mod_header.
Check the HTTPD documentation for usage of these 2 modules.
