Hi,

I am trying to understand php_session_cache_limiter but my knowledge
is, well, limited :)

Setting session.cache_limiter to an empty string doesn't send headers.
Is this just an artefact of if (!strcasecmp(lim->name,
PS(cache_limiter))) not matching the empty string or does if
(PS(cache_limiter)[0] == '\0') return 0; deliberately stop it?

Ie. what should I add to the documentation for people who don't want
PHP to send anything?

Thanks

Karoly Negyesi

If I remember correctly, old doc was referred as "none". Any invalid
cache limiter name will be ignored, though.

It may be good idea to raise notice error for invalid limiter name and
introduce "none" limiter.

Any comments?

Hi Karoly,

Failing silently in case of typo is not good.
Could you file feature request to bugs.php.net?

I'll make patch for trunk and commit it unless there is objection.
