Redirects all contents of the directories http://site.ru/dir1/any/any → to site.ru dir2 /any/any .

RewriteCond %{REQUEST_URI} ^/dir1/(.*)$ 
# если строка начинается с /dir1/ 
RewriteRule ^(.*)$ /dir1%1 [R=301,L]

#Redirect all urls starting with dir1 to dir2 preserving further URL structure
Redirects all contents of /any/dir1/any/any → to /any/dir2/any/any

RewriteCond %{REQUEST_URI} ^(.*)/dir1/(.*)$ 
# если строка содержит /dir1/ 
RewriteRule ^(.*)$ %1/dir2/%2 [R=301,L]

#Redirect all urls starting with dir1 to dir2 preserving further URL structure
