列出 IE5 所支持的所有server端变量

以下是MSDN (1999年4月版)提供的 IE5 所支持的所有server端变量
部分变量在以前的版本中不支持,而且在以后的版本中可能会有变化(这是Microsoft的原话)
Variable Description
ALL_HTTP All HTTP headers sent by the client.
ALL_RAW Retrieves all headers in the raw-form. The difference between ALL_RAW and ALL_HTTP is that ALL_HTTP places an HTTP_ prefix before the header name and the header-name is always capitalized. In ALL_RAW the header name and values appear as they are sent by the client.
APPL_MD_PATH Retrieves the metabase path for the (WAM) Application for the ISAPI DLL.
APPL_PHYSICAL_PATH Retrieves the physical path corresponding to the metabase path. IIS converts the APPL_MD_PATH to the physical (directory) path to return this value.
