last-modified

It would also be neat to enable template plugins to ask the data sources for last-modified timestamps on objects.

If just given a timestamp it would generate an ETag from the timestamp by hashing it; if just given an ETag, it would generate a last-modified timestamp by comparing the ETag to one stored in a database.

Well, I think that caching is key enough that the data source interface convention should be extended to return a list consisting of the data object and a last-modified timestamp, to support caching.

But for extensions that add new features rather than just return extra information, such as extending the the file type handlers to support URL generation and computing an overall last-modified timestamp without rending the result, it would set a good precedent for future expansion with backwards compatability to just add extra environment entries be made for extended functionality.

This should probably be abstracted out; a file type handler should perhaps be extended from a simple procedure to a more complex object with procedures to compute last-modified dates for the entire page as well as to generate the content.

The effective last-modified date of a page would be the latest last-modified date of any loaded data source, and the source of the page itself and any templates it uses.

File system items in data objects cache a bunch of useful pieces of information, such as the last-modified time, file creation time, last-access time, the file size, the file attributes, and the file name both long and short.

For example, I want to know the size of the link target, its last-modified time, and its name.

Ideally I'd order the text files by last-modified dates so that we could do a time analysis on the database.

Using lat-modified HTTP header for threads and CMS articles I would like to have HTTP last-modified header used at least for threads (showthread. php), and probably for CMS articles.
