问题：配置Apache，httpd.conf

添加虚拟目录

<IfModule alias_module>
      Alias /sww/ "C:/xampp/htdocs/test/"
</IfModule>

出现限制权限访问，

Access forbidden!

You don't have permission to access the requested object. It is either read-protected or not readable by the server.

If you think this is a server error, please contact the webmaster.

Error 403

需添加目录设置

<Directory "C:/xampp/htdocs/test/">

    AllowOverride None

    Options None

    Order allow,deny

    Allow from all

</Directory>

尝试：

1.  将C:/xampp/htdocs/test/的/去掉，结果：无法启动apache

2.  将C:/xampp/htdocs/test/的/改成\，结果：无法启动apache

3.  将C:/xampp/htdocs/test/改为"D:/Work/Booksir/BP/Code/User_Booksir_com_cn/trunk/"，结果：无法启动apache

4.  C:/xampp/htdocs/test/文件夹有Everyone完全控制权限，给D:/Work/Booksir/BP/Code/User_Booksir_com_cn/trunk加上Everyone的完全控制权限，结果：仍无法启动apache

5.  将"D:/Work/Booksir/BP/Code/User_Booksir_com_cn/trunk/"的/去掉，/sww/的/去掉，结果：成功启动apache

结论：

最好

Alias /sww "D:/Work/Booksir/BP/Code/User_Booksir_com_cn/trunk"

<Directory "D:/Work/Booksir/BP/Code/User_Booksir_com_cn/trunk">

后面都不要加/，都不要使用\，这样比较保险

    # If you include a trailing / on /webpath then the server will

    # require it to be present in the URL.  You will also likely

    # need to provide a <Directory> section to allow access to

    # the filesystem path.
