不需要的页面重定向（特别是在Safari中）

Question

我们的'projects'目录中的页面偶尔会重定向到根域，而无需用户输入任何内容。例如，此处的项目：http://www.mywebsite.com/projects/this-is-the-page/123将加载然后重定向到http://www.mywebsite.com - 这几乎总是发生在Safari中，但并不总是在其他浏览器中。通常重新加载原始页面会使其“粘住”而不是重定向。这种行为是否符合您的经历？该站点使用CodeIgniter框架。有关您的信息，我们的.htaccess文件竞争如下所示：

RewriteRule ^test.php$ mod_rewrite.php
