ETag et al

[ #18258 ]
Dear All,

I'm thinking about adding ETag support to XML::RSS::TimingBot, but I wonder if it's worth the bother. Are there actually HTTP servers that support ETag/If-None-Match that don't also support Last-Modified/If-Modified-Since?

(I already have XML::RSS::TimingBot doing Last-Modified/If-Modified-Since)

  • I'm not sure how widespread it is, but I can tell you that the in-house code at my former employer used ETags without Last-Modified support, so it does exist.
    • For Slash, we do some dynamic RSS now (and plan to roll out even more), and use ETag for it.

      Why dynamic? So http://use.perl.org/index.pl?content_type=rss&logtoken=... will give you RSS matching your own prefs. So you can include the daily module listings, or exclude user group meetings, etc.
