BTW: This list if for development *of* Zope, the [EMAIL PROTECTED] list is better for questions bout developing *with* Zope.
On to your question: There is no automatic way in which DTML can do this for you. This is simply because <dtml-var foo> doesn't tell Zope what foo is. Is it a document or a script that returns something different every time it is called or something else? In fact foo might different things at different times, if you aquire the template into different contexts. Anyhow, if you really want to set a Last-Modified header that reflects the latest of a group of documents, you can write a python script that accepts either a list of names or objects to test. For the latter here's a Py script named "setLastModTime" with a single argument, "*objects": last_mod = objects[0].bobobase_modification_time() for ob in objects[1:]: last_mod = max(last_mod, ob.bobobase_modification_time()) context.REQUEST.RESPONSE.setHeader('Last-Modified', last_mod.rfc822()) return last_mod # for debugging purposes Then from dtml: <dtml-call expr="setLastModTime(this(), fooMethod, barDocument, ...)"> hth, Casey On Fri, 2002-06-14 at 00:10, Wei He wrote: > Hi all, > > Say you have 1_html with only one line: > <dtml-var 2_html> > > When you HEAD http://xxx/1_html, you get Last-Modified refelecting only > the last modification time of 1_html, while most people is expecting it > to be newer one of 1_html and 2_html. > > Does anyone know of a walk-around like using the max() of > bobobase_modification_time().timeTime() on the document itself > and all the componets it dtml-vared? > > Forgive my using of non-Zope terms, for I'm new to Zope/Python. > > Wei He > > > > _______________________________________________ > Zope-Dev maillist - [EMAIL PROTECTED] > http://lists.zope.org/mailman/listinfo/zope-dev > ** No cross posts or HTML encoding! ** > (Related lists - > http://lists.zope.org/mailman/listinfo/zope-announce > http://lists.zope.org/mailman/listinfo/zope ) _______________________________________________ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
