That's what I meant :) In order to implement the document.lastModified
property in JS I need the information from somewhere. To see whether
that value is gathered anywhere in the first place I checked the IO
slave. Since the RFC says

13.3.1 Last-Modified Dates

   The Last-Modified entity-header field value is often used as a cache
   validator. In simple terms, a cache entry is considered to be valid
   if the entity has not been modified since the Last-Modified value.

I thought that it might be already used somewhere for caching purposes.
Seems like it isn't.

Harri.
