PHP version: 4.2.1
PHP Bug Type: Session related
Bug description: Expires header incorrectly set, cannot be overwritten
When using sessions, the Expires header is set to a date in the past (1981)
instead of being correctly calculated from the current date plus the
session expire time. This leads to re-loading of the resource instead of
using cached data in browsers that obey the Expires header and/or use HTTP
1.0.
Additionally, it is not possible to replace the Expires header using the
header() function. Trying to do so results in the new correct date being
appended after the old incorrect one (separated by a comma) which makes no
sense.
The only way to achieve correct Cache-Control and Expires headers is to
switch off the automatic session headers by calling
session_cache_control('none'), and then set all headers on one's own.
However, this is only a work-around.
