I am working on a little framework where I have this directory tree:

project/
|--- ... (directories unrelated to the question)
|--- public/
|     |--- index.php
.htaccess

The .htaccess sends every request to project/public/index.php but I have to add specific rules for assets (stylesheets, js, images, ...).

Searching a lot I started adding a RewriteCond for specific extensions as I saw almost everywhere, and RewriteRule to catch parts of the URL starting with folder names like css/ etc:

# Send front-end assets in the public directory
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} \.(bmp|css|gif|ico|jpe?g|js|png|tiff)$
RewriteRule ((css|js|img)\/.*\..*)$ public/$1 [L,QSA]

But this means I would define which extensions are allowed. And this would also mean I would define a specific list of subdirectories allowed in public/.

I'm not an expert with mod_rewrite, but I just thought I could define an "assets prefix" which, if present in URL, would rewrite the rest of the URL to the public directory.
Example URL:

                   | detect | rewrite to /public/$1
some_route_to_strip/_prefix_/any_custom_dir/any_file.ext
  • Should I avoid doing that ? If so, why ?
  • If not, is the way to handle requests to asset files I almost always encountered a good way to do ?

  • Why...........? Commented Feb 19, 2020 at 15:46
  • @user253751 using an arbitrary string to detect when an URI is looking for assets could be easier and more reliable than filtering by file extension. Commented Feb 20, 2020 at 10:33
  • But why not just use the actual path? Instead of telling the browser to fetch /a/b/c/foo.css and then rewriting it to /public/foo.css why not tell the browser to fetch /public/foo.css? Commented Feb 20, 2020 at 10:37
  • @user253751 The idea was to link assets with /_front/foo.css which would rewrite to /public/foo.css to avoid rewriting to the Front Controller like /public/index.php?_url=/public/foo.css. But I think I was wrong about my .htaccess configuration at the time I wrote that, this can be served directly, only the application should write the correct path to the assets.
