Apache: Except a path from RewriteRule

I'm trying to except from being redirected to /portal/ if you access to /sitemapHT/ but it seems that this process ^(/$|!sitemapHT) is wrong, since it still redirecting me to /portal/

<VirtualHost *:80>
        DocumentRoot "/opt/tomcat-5.5.30/webapps/portal"
        ServerName hoteles
        ServerAlias hoteles

        JkUnMount       /images/*.gif           w1
        JkUnMount       /images/*.png           w1
        JkUnMount       /images/*.jpg           w1
        JkUnMount       /js/*.js                w1
        JkUnMount       /styles/*.css           w1


        JkMount         /portal                 w1
        JkMount         /portal/*               w1


        RewriteEngine on
开发者_Python百科        RewriteCond %{REQUEST_METHOD} ^(TRACE|TRACK)
        RewriteRule .* - [F]
        Options +FollowSymlinks

        RewriteRule   ^(/$|!sitemapHT)  /portal/  [R]
        RewriteRule ^/(?!portal)(.*) /portal/ficha.action/$1 [PT]

</VirtualHost>

Could you suggest me a proper correction?

Thank you!

I hope I understood you correctly:

RewriteCond $1 !^/(sitemapHT/|portal/)
RewriteRule ^(.*) /portal/ [R,L]

This will redirect (302 code) ALL incoming requests to /portal/ EXCEPT /sitemapHT/ or when requesting /portal/ directly.

UPDATE:

RewriteCond $1 !^/(sitemapHT/|portal/)
RewriteRule ^(.*) /portal/ [R,L]
RewriteCond $1 !^(sitemapHT/|portal/)
RewriteRule ^/(.*) /portal/ficha.action/$1 [PT]

Use the above rules instead of your last 2 lines:

RewriteRule ^(/$|!sitemapHT) /portal/ [R]
RewriteRule ^/(?!portal)(.*) /portal/ficha.action/$1 [PT]
