[Zope-CMF] Plone page caching

[David (Hamish) Harvey]

Folks,

I was hoping to be able to postpone looking at caching, and expect my users 
to be patient in the first few weeks. Unfortunately, it seems that 
something has changed over the last week or so with the caching in Plone. 
I'm using CMF 1.3b1 and tracking the Plone CVS.

I find now that if I, for example, go to the front page, log in, then go 
back to the front page, I get the old version which says I'm not logged in. 
Similarly, if I edit a document, save the changes, then up pops the 
unedited version from a cache somewhere. All this happens without any cache 
manager in the in the site folder or the root folder.

Has anyone any hints? In the first instance I'd be interested to know how I 
can disable caching.

Where can I find info on setting caching headers for page templates? 
Searching the Plone code all I can find is that the headers are set on css 
stylesheets.

Cheers,
Hamish
