.htaccess URL Rewrite to Subdirectory

Question

What is the best method to rewrite anything below "/some/subdir" to "/some/subdir/projects" like from this:

http://www.mydomain.com/some/subidr/test/

... to this:

http://www.mydomain.com/some/subdir/projects/test/

I found a similar question posted, but the solution didn't seem to work in my case. My current attempt so far (which doesn't seem to work):

Options +FollowSymLinks
RewriteEngine On

RewriteCond %{REQUEST_URI} !^/projects/.*$
RewriteRule ^(.*)$ /projects/$1 [L]

EDIT: I forgot to mention the .htaccess file would have to be sitting within /some/subdir as I don't have write access to the server's web root.

Answer 1

This is the solution I finally got to work:

RewriteEngine On

RewriteCond %{REQUEST_URI} !^/some/subdir/projects/.*$
RewriteRule ^(.*)$ /some/subdir/projects/$1 [L]

Answer 2

Try this rule in your .htaccess configuration file in the document root of your server:

RewriteEngine on
RewriteRule !^some/subdir/projects(/|$) some/subdir/projects%{REQUEST_URI} [L]

---

As you want to use this rule in your /some/subdir/ directory, change the rule as follows:

RewriteRule !^projects(/|$) projects%{REQUEST_URI} [L]

And if you want to redirect any requests of /some/subdir/projects/foobar to /some/subdir/foobar, put this rule above the previous mentioned:

RewriteCond %{THE_REQUEST} ^[A-Z]+\ /some/subdir/projects[/?\s]
RewriteRule ^some/subdir/projects/?([^/].+)?$ /some/subdir/$1 [L,R=301]
