I would like to have HTTP last-modified header used at least for threads (showthread.php), and probably for CMS articles. Information for that is present in the database (and in fact it is used by different sitemaps generators).
Do anybody know a way to use last-modified header in vBulletin? Any existing mod? Manual?
I don't beleive that nobody did this before, but unforunately I was not able to find anything relevant via forum search.
