Typographers, One question that has been bugging me about Typo for a while now is: does Typo emit Etag or Last-Modified HTTP headers, suitable for web caches to use? This is particularly important for the oft-requested feeds.
Today I finally took the time to find out. The answer seems to be that Typo doesn't emit either of these headers. So, the obvious next question is: how hard is it to add one of these headers? And what about the corresponding conditional GET? Dan Kubb's REST controller for rails (http://onautopilot.com/oss/ rails/rest_controller.rb) looks to provide a leg-up, but we still need to calculate the actual header ETag and Last-Modified values. These need to be set as instance variables in the XML controller. Could the *_feed.rxml views be used to set these? In particular it looks like the Last-Modified value could be set from prettymuch the same value used for the Atom "updated" field (ie @items.first.updated_at.xmlschema) - a fairly low impact change I would think? ETag might need something a big more sophisticated... This is obviously not very well thought through, but are there any initial reactions? _______________________________________________ Typo-list mailing list [email protected] http://rubyforge.org/mailman/listinfo/typo-list
