RewriteMap problems

RewriteMap problems
How can i use RewriteMap and work with Alias (not affect the alias redirection) on Virtual Host?
I hv no idea.

<VirtualHost *:80>
DocumentRoot /var/www/html
ServerName resource.centos6-gordon.japan
ErrorLog logs/error_log_192
CustomLog logs/access_log_192 common

RewriteEngine on
Rewritelog /var/log/httpd/rewirte_log
Rewriteloglevel 9

RewriteMap redirectmap "txt:/etc/httpd/conf/mapredirect"
RewriteRule "^/~?([^/]+)(/?|.*)$" ${redirectmap:$1|%{REQUEST_URI}} [PT]

Alias /ming /home/Gordon/Ming
Alias /dora /home/Gordon/Dora

</VirtualHost>



rewirte_log
Code:
RewriteRule "^/~?([^/]+)(/?|.*)$" ${redirectmap:$1|%{REQUEST_URI}} [PT]

(2) rewrite '/gordon' -> '<URL>'
(2) implicitly forcing redirect (rc=302) with <URL>
(2) forcing '<URL>' to get passed through to next API URI-to-filename handler



RewriteRule "^/~?([^/]+)(/?|.*)$" ${redirectmap:$1|%{REQUEST_URI}}

(2) implicitly forcing redirect (rc=302) with <URL>
(1) escaping h<URL> for redirect
(1) redirect to <URL> [REDIRECT/302]
