关于Apache URL映射和PHP会话

所以我的问题总结如下：

我有这样一个表单（为了示例起见，在第X页中），它将数据提交到一个处理页面，该页面的地址是Apache的RewriteAlias映射的URL。该表单的操作URL有一个会话哈希键作为GET查询，这是它进行查询所必需的，并且这会随着每个用户的每次页面加载而变化。当您在处理页面中时，该会话哈希不会更改。通常情况下它会通过，但在这种情况下它不会。

经过一段时间的调查，我发现发生这种情况的最可能原因是，当Apache处理包含所有重写条件的.htaccess文件并更改映射页面X中的会话哈希键时，映射的URL一定以某种方式重定向到了页面中。当我使用X页的原始未映射URL时，我发现了这一点（它将是index.php？snowblobe=｛snowblobe｝，而不是/sg/{snowblobe}。我不知道是什么导致映射的URL更改了会话哈希，也不知道如何解决这个问题。

包含会话哈希的PHP代码段

    if(!isset($_GET['verify'])){     $_SESSION['temp_n'] =   md5(microtime(true));} //this changes at every page except the processing page

.htaccess文件
