Req #73377 [NEW]: Verbose caching instructions by default.

From: inforbano at gmail dot com Operating system: PHP version: Irrelevant Package: PHP options/info functions Bug Type: Feature/Change Request Bug description:Verbose caching instructions by default. Description: ------------ When function session_start(); is used with default options, PHP generates headers like this: Expires: Thu, 19 Nov 1981 08:52:00 GMT Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Pragma: no-cache This verbose behavior is wrong for the following reasons. Most PHP-programmers do not need to know anything about caching. Therefore user agents (browsers, proxies, robots...) MUST have rational behavior (with respect to caching) without any special instructions from the server. This is only problem of user agents to understand cookies and to automatically adjust their caching behavior according to their needs. On the other hand, some meticulous PHP-programmers investigate HTTP-headers of their sites to be sure that everything is fine. And in this case they just waste their time to study problems, that are not their. Test script: --------------- <?php session_start(); Expected result: ---------------- No special headers for caching by default. This is like session_cache_limiter(''); is set by default. Actual result: -------------- Expires: Thu, 19 Nov 1981 08:52:00 GMT Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Pragma: no-cache -- Edit bug report at https://bugs.php.net/bug.php?id=73377&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=73377&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=73377&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=73377&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=73377&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=73377&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=73377&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=73377&r=needscript Try newer version: https://bugs.php.net/fix.php?id=73377&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=73377&r=support Expected behavior: https://bugs.php.net/fix.php?id=73377&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=73377&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=73377&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=73377&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=73377&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=73377&r=dst IIS Stability: https://bugs.php.net/fix.php?id=73377&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=73377&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=73377&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=73377&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=73377&r=mysqlcfg
