301重定向不起作用（我知道另一个）

Question

Yes, I checked the related questions posted in SO, but could not find something that would help me.

My .htaccess has plenty of redirects already, and they work fine, but this one is giving me the go around.

I had a URL like:

http://example.com/comp_all.php?vid_mod=529

which I changed to a more friendly one:

http://example.com/comparatif-voiture/Audi/A4/529

In order to accomplish that I added the following rule within .htaccess:

RewriteCond %{REQUEST_URI} ^/?comparatif-voiture [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ([0-9]+$) /comp_all.php?vid_mod=$1 [L]

And that works fine, as well.

Now, I want to have the 'old and ugly' URL still sitting out there to be redirect to the 'nice' ones.

I tried the following:

Redirect 301 /comp_all.php?vid_mod=529 http://example.com/comparatif-voiture/Audi/A4/529

But that does not work. It just shows the 'ugly' URL.

It does not matter whether I placed the above redirect before or after the Rewrite Rule.

You cannot use query string in Redirect directive. You need RewriteCond in mod_rewrite like this:

RewriteEngine On

RewriteCond %{THE_REQUEST} \s/+comp_all\.php\?vid_mod=([0-9]+) [NC]
RewriteRule ^ /comparatif-voiture/Audi/A4/%1? [R=301,L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^comparatif-voiture/.+?/([0-9]+)/?$ /comp_all.php?vid_mod=$1 [L,QSA]

PS: I have also simplified your other rule.
