- .. _reference.feed.ttl:
- :py:attr:`feed.ttl`
- ===================
- According to the :abbr:`RSS (Rich Site Summary)` specification, "None"
- No one is quite sure what this means, and no one publishes feeds via
- file-sharing networks.
- Some clients have interpreted this element to be some sort of inline caching
- mechanism, albeit one that completely ignores the underlying :abbr:`HTTP
- (Hypertext Transfer Protocol)` protocol, its robust caching mechanisms, and the
- huge amount of :abbr:`HTTP (Hypertext Transfer Protocol)`-savvy network
- infrastructure that understands them. Given the vague documentation, it is
- impossible to say that this interpretation is any more ridiculous than the
- element itself.
