So I click “read new posts” and get a page of threads. Open up the 7 or 8 of them that I am interested in in separate windows and read them. Somewhere on this page is a thread, e.g., “Die, Gibbon Girls, Die”. I finish reading the threads I want to read from this page and click the “Next Page” link at the bottom of the page of threads.
New page of threads opens up. Ninth from the top is “Die, Gibbon Girls, Die”.
OK, question: when the “Next Page” link is clicked, does it send cgi back that says, in essence, “For the time and date at which this particular user originally clicked ‘read new posts’, please show the second page of what were new threads as of that time, sorted by what were most recent posts as of that time”? (If so, why the second appearance of ‘Gibbon Girls’?). Or does it instead send cgi back that says, in essence, “Please once again find all the threads with posts that are newer that date on which this poster previously visited the board, and this time go to the second page, sorting by most recent posts as of now”?
If it is doing the second of these, that means that when I click “Next Page” there are posts on the (hypothetical) first page that I never saw, because the sort order has changed and/or new posts have been added to posts that would have been on page 2 when I was on page 1 but are on page 1 now that I am on page 2, right?
Whaddaya mean, your head hurts?
