Thanks, that's what I was missing; I've been using an older version of WW and browsed CVS and didn't see anything there. I mean to use this for RSS generation and the various RSS readers are not necessarily well-written, so I'd rather support both modified-since and etag. I'll look into hacking support into the adapter for etag as well.
Thanks!

There is no API to get at the HTTP headers in general. But the If-Modified-Since header is handled as a special case, to make client-side caching of static objects possible. You can get it this way:
ims = self.request().environ().get('If-Modified-Since')
The adaptor sets this up; see Adapters/mod_webkit*/mod_webkit.c.
WebKit/HTTPServlet.py defines a "lastModified()" method that subclasses may override to define an object's age. The default age is None (don't know, therefore don't cache). For static files, it is the file's mod time; see WebKit/UnknownFileTypeServlet.py.
If you need access to the Etag header or others, you'd need to hack the adaptors in a similar way.
