[Zope] Prevent cache from being loaded in Zope/DTML

[Mohan Baro]

Maybe I am asking the wrong question.

How do I get Zope to reload a page from the server when the user hits the
BACK button of the browser.

I tried

<dtml-call expr="RESPONSE.setHeader('Expires', 'Tue, 1 Jan 1980 12:00:00
GMT')">

and

<dtml-call expr="RESPONSE.setHeader('pragma', 'no-cache')">
<dtml-call expr="RESPONSE.setHeader('expires', '0')">


They are not working.



Mohan.

<dtml-call expr="RESPONSE.setHeader('Expires', 'Tue, 1 Jan 1980 12:00:00

There might be a simpler syntax but I know this works everywhere.  (The
header name might be "Expiration", though.)
