Sorry, was out of town for a while and unable to keep up with the list.  Did
you get this to work?

The only references I've found are here: (URL may wrap)

http://marc.theaimsgroup.com/?l=xml-cocoon-dev&m=102242010332543&w=2

I've not used it myself.  If you need more specific information
ask on the dev list of the people involved in this thread.

If you do manage to get this to work, would you mind terribly if
I asked you to post a FAQ?

Thanks,

J.

Re: No-caching for SVG's

[Spectron International, Inc.]

I'm using 2.1dev (HEAD?) and the browser is IE and/or Netscape. I'm already
using the .

This works for the page but not the SVG inside the page. Right now when I
click on a link that will display an SVG it works, but if I click 'Back' and
then click on the same link again it changes the page contents but not the
SVG, I have to click on 'Refresh' to update the graph. Is there a way to
refresh the SVG as well?

I read here, that if I sent an 'Expires' or 'Last modified' header to the
browser, the graph wouldn't be cached by the browser, and that HEAD had the
'Expires' changes. I just want to know how to use Expires or what should I
do to add headers to the response in Cocoon. Should I make a new serializet,
can I use an action?

I think you got drown'd in a thread war, sorry :)

You don't say what version of Cocoon you are using or what
browser you are targeting.  The way around this (for the
latest cvs version of Cocoon) is to wrap anything you don't
want caching in a



pipeline.

Give it a try, it works for me ;)

Re: No-caching for SVG's

[Spectron International, Inc.]

Found that EXPIRES was added to HEAD in this message:

http://marc.theaimsgroup.com/?l=xml-cocoon-users&m=102343531609919&w=2

Now, what do I have to add to the sitemap to make it work?

RE: No-caching for SVG's

[Geoff Howard]

I think that browsers are more aggressive caching images than html.  The
assumption seems to be that images do not change as often.  That's not
authoritative, just my theory from experience trying to do things like what
you're doing.  The good news is that browsers should respect a last-modified
http header, and/or an expires header set in the past.  Probably the second
is more important.  What I don't know is if cocoon has currently working
functionality to set those headers.  I remember a past discussion where I
thought this was in the process of being fixed.
