将文件夹重写到该文件夹​​内的另一个子文件夹

Question

I'm trying to convert a request from a folder, to another sub-folder inside that folder. Let me explain:

Convert: localhost/myproject/build/css/style.css

To: localhost/myproject/build/dev/css/style.css

So, I need to add '/dev' to the request after 'build/' folder. What I have?:

RewriteCond %{HTTP_HOST} ^localhost$ [NC]
RewriteRule ^build/(.*) build/dev/$1

And I'm getting an infinite loop from Apache:

[Thu Apr 24 17:56:39.721756 2014] [core:error] [pid 6980:tid 1660] [client ::1:55569] AH00124: Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.

And I know what is happening, Apache is doing this:

build/css/style.css (original request)
build/dev/css/style.css 
build/dev/dev/style.css
build/dev/dev/dev/style.css
.... to the infinite

So I only need to catch an rewrite the request once. Any idea?

Answer 1

This should work:

RewriteCond %{HTTP_HOST} ^localhost$ [NC]
RewriteCond %{REQUEST_URI} !^/build/dev/(.*)
RewriteRule ^build/(.*) /build/dev/$1 [R=301]

The above will check and see if build/dev/ is in the url already, it is the it won't redirect. You were getting it to add dev/ if build/ was in the url, which caused the redirect loop.

Answer 2

You need to use a condition to skip adding /dev once it has been added:

RewriteCond %{HTTP_HOST} ^localhost$ [NC]
RewriteRule ^build/((?!dev/).*)$ build/dev/$1 [L,NC]
