htaccess重定向除基本URL外的所有链接

Question

I want to redirect all links from my site except the home url to subdirectory.

Example:
www.example.com should remain www.example.com

www.example.com/someurl should redirect to www.example.com/sub/someurl

www.example.com/someurl/anothermore should redirect to www.example.com/sub/someurl/anothermore

Edit: I am currently working on a subdirectory so currently its www.example.com/main/someurl to redirect to www.example.com/main/sub/someurl

Answer 1

To redirect everything to the /sub subdirectory, except the root then you can do something like the following at the top of your .htaccess file in the document root using mod_rewrite:

RewriteEngine On

RewriteCond %{REQUEST_URI} !^/sub/
RewriteRule !^(index\.php)?$ /sub%{REQUEST_URI} [R,L]

The above states that if the request is not / (or /index.php ) and does not start /sub/ (the RewriteCond directive) then redirect to /sub/<suburl> .

Edit: I am currently working on a subdomain so currently its www.example.com/main/someurl to redirect to www.example.com/main/sub/someurl

That's a subdirectory, not a "subdomain". (?)

If this is the case then move these directives to a /main/.htaccess file and change them to read:

RewriteCond %{REQUEST_URI} !^/main/(index\.php)?$
RewriteCond %{REQUEST_URI} !^/main/sub/
RewriteRule (.*) /main/sub/$1 [R,L]
