1550 // (The root of the problem is clearly a PHP bug.)

1554 // relative to correct basepage.

1559 // Revision 1.72 2003/02/17 02:19:01 dairiki
1560 // Fix so that PageHistory will work when the current revision
1561 // of a page has been "deleted".
1563 // Revision 1.71 2003/02/16 20:04:48 dairiki
1564 // Refactor the HTTP validator generation/checking code.
1566 // This also fixes a number of bugs with yesterdays validator mods.
1568 // Revision 1.70 2003/02/16 05:09:43 dairiki
1569 // Starting to fix handling of the HTTP validator headers, Last-Modified,
1572 // Last-Modified was being set incorrectly (but only when DEBUG was not
1573 // defined!) Setting a Last-Modified without setting an appropriate
1574 // Expires: and/or Cache-Control: header results in browsers caching
1575 // the page unconditionally (for a certain period of time).
1576 // This is generally bad, since it means people don't see updated
1577 // page contents right away --- this is particularly confusing to
1578 // the people who are editing pages since their edits don't show up
1579 // next time they browse the page.
1581 // Now, we don't allow caching of pages without revalidation
1582 // (via the If-Modified-Since and/or If-None-Match request headers.)
1583 // (You can allow caching by defining CACHE_CONTROL_MAX_AGE to an
1584 // appropriate value in index.php, but I advise against it.)
1588 // o Even when request is aborted due to the content not being
1589 // modified, we currently still do almost all the work involved
1590 // in producing the page. So the only real savings from all
1591 // this logic is in network bandwidth.
1593 // o Plugins which produce "dynamic" output need to be inspected
1594 // and made to call $request->addToETag() and
1595 // $request->setModificationTime() appropriately, otherwise the
1596 // page can change without the change being detected.
1597 // This leads to stale pages in cache again...
1599 // Revision 1.69 2003/01/18 22:01:43 carstenklapp
