.htaccess不会从旧网址重定向到新网址3

Question

I am new in .htaccess . I have read the documentation, but couldn't make the redirect rule work.

I want RewriteRule for following

http://mywebsite.com/restaurants/59393/the-grounds-of-alexandria.htm

to

http://mywebsite.com/restaurants/the-grounds-of-alexandria

I have tried out this

RewriteRule ^(.*)/[0-9]/(.*)$ ^(.*)/(.*)/$ [R=301,L]

Also how can u get the subdomain and put it to the front of all links, like this

http://sydney.mywebsite.com/restaurants/59393/the-grounds-of-alexandria.htm

to

http://mywebsite.com/sydney/restaurants/the-grounds-of-alexandria

but no result.

Answer 1

Rewrite this is simple:

http://mywebsite.com/restaurants/59393/the-grounds-of-alexandria.htm
to
http://mywebsite.com/restaurants/the-grounds-of-alexandria

Your rewrite rule RewriteRule ^(.*)/[0-9]/(.*)$ ^(.*)/(.*)/$ [R=301,L] is too global for the urls. Second of all you just say [0-9] with means only one digit.

RewriteRule ^([^/]+)/[0-9]+/([^.]+)\.htm$ /$1/$2 [R=301,L]

Try this one ;)

Edit (for second question):

http://sydney.mywebsite.com/restaurants/59393/the-grounds-of-alexandria.htm
to 
http://mywebsite.com/sydney/restaurants/the-grounds-of-alexandria

Sure ;) There you have to work with RewriteCond.

RewriteCond %{HTTP_HOST}%{REQUEST_URI} ^([^\.]+)\.mywebsite\.com/([^/]+)/[0-9]+/([^.]+)\.htm
RewriteRule ^.*$ http://mywebsite.com/%1/%2/%3 [R=301,L]

For explanation, the %1-3 can be used from the previous match to be used in the RewriteRule Statement. This should work for every subdomain and only for subdomains. If you want a specific subdomain you can adjust the first line to ^(sidney|othersubdomain|anothersubdomain)\\.mywebsite\\.com... .
