Redirect permanent, www redirect & url rewriting - .htaccess

Question

I gave an old website a new CMS. Now i need a .htaccess with 3 parts, but it only works with 2 of them:
Redirect permanent
www redirect (this don't work)
url rewriting
Now i 'll explain something more.
Part 0 (only for the totality)
RewriteEngine On
Part 1 (Redirect permanent) i use to redirect the URLs of the old CMS to the content of the new one.
RewriteCond %{THE_REQUEST} !/de-old-content.html
Redirect permanent /de-old-content.html /old/content.html
Part 2 (www redirect) i use to avoid duplicate content.
RewriteCond %{HTTP_HOST} ^website.de [NC]
RewriteRule ^(.*)$ http://www.website.de/$1 [L,R=301]
Part 3 (url rewriting) to convert "old/content.html" into "index.php?adresse=old/content"
RewriteRule ^(.*)\.html$ index.php?adresse=$1 [l,qsa]
the [l,qsa] only allows to use $_GET.
Is it possible to combine this parts?
If i use Part 2 it shows the right content with
http://www.website.de/abc/def/ghi.html
but without www it redirect to
http://www.website.deabc/
I think there must be a misstake in this Part.
Thanks in advance.

Answer 1

Redirect is part of mod_alias, while RewriteCond and RewriteRule are part of mod_rewrite. As a consequence the RewriteCond of part 1 accually applies to the RewriteRule of part 2, which would make it not work properly.
Best to avoid using both rewriterule and redirect together.
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^website.de [NC]
RewriteRule ^(.*)$ http://www.website.de/$1 [L,R=301]
RewriteRule ^de-old-content\.html$ /old/content.html [L,R=301]
RewriteRule ^(.*)\.html$ index.php?adresse=$1 [L,QSA]
PS. to keep your sanity, use 302's while testing. Once everything is working, change them to 301's. Since you already used 301's, also clear your browser cache, so all the old 301's are removed from the browser's cache.
