PHP 5.2.3 Released [01-Jun-2007] The PHP development team would like to announce the immediate availability of PHP 5.2.3. This release continues to improve the security and the stability of the 5.X branch as well as addressing two regressions introduced by the previous 5.2 releases. These regressions relate to the timeout handling over non-blocking SSL connections and the lack of HTTP_RAW_POST_DATA in certain conditions. All users are encouraged to upgrade to this release. Further details about the PHP 5.2.3 release can be found in the release announcement for 5.2.3, the full list of changes is available in the ChangeLog for PHP 5.

$etag = date('YmdH'); if ($_SERVER['HTTP_IF_NONE_MATCH'] == $etag) { header('HTTP/1.1 304 Not Modified'); } else header('Etag: '.$etag);

用以上代码控制页面缓存，IE下刷新就能更新缓存，firefox下刷新不起作用要等到缓存过期，必须手动去清理页面缓存才能更新。 唉！

迅雷的镜像搜索功能确实是它可圈可点的地方，至少去sf下东西不用在去选下载点，直接下载就是，它自动会把添加相关的镜像。 可问题也比较多，首先就是广告，这年头带广告的下载软件还真是不多见了，不过我从来没用过原版的迅雷的，一般都是下载去广告的。 还有个问题就是tnnd它非要占80端口，害我每次用apache就非关掉它，然后再重新开。 还有个下bt的问题，说到bt下载，迅雷这方面做的还真是不错，连接速度真是其它相关bt下载软件所不具备的，下载的稳定性也不错。至少我用bitcomet,flashget相比都逊色好多了。但人性化方面就比较差了，比如，一旦选定下载目录就不能更改了，我下载连续剧有的上百集（这个有点变态）单分区比较小，往往需要下载了一半，另一半要换到另外一个分区去。它居然不能更改下载目录，只是把任务删除了，重新添加下载了更换，这一点操作上bitcomet就做的很好，更换目录很方便。 还有就是bt下载程序上不太稳定，偶尔会出现非法操作。
