Hi,
For a particular PHP installation I wanted to turn off all
'Cache-Control' headers, because 'cache_limiter=nocache' requires a user
to explicitly resubmit form data every time and 'cache_limiter=private'
would cache forms too often.
However the current cache_limiter implementation does not have an option
to do so. So I wrote a trivial patch against PHP 4.2.3 that adds value
'none' to session.cache_limiter. When set PHP replies do not include
'Cach-Control' or 'Pragma: nocache' headers, just a 'Last-Modified' one.
Please consider merging it, from browsing the mailing list I get the
impression that other people may find the 'none' option useful too.
Thanks,
Bastiaan Bakker
