.htaccess mod_rewrite subdirectory to URL parameter

Question

I hope this was not asked over and over again before, but I didn\'t get further to an answer using google, w3schools and so on. So here is my question: I\'m writing a script

Answer 1

Following what you ask, this is important not to do a redirect, but let the rewriterule modify internally the URL i.e. the RewriteRule should not end with [R,L] but rather [L] and maybe the "query string append" directive to keep what's after the ? so this should probably be [QSA,L].

Now here's how I'd do to avoid rewriting static files: if it's not a file then (and only then) test it:

# if it's not a file...
RewriteCond %{SCRIPT_FILENAME} !-f
# ... and it's a dir
RewriteCond %{SCRIPT_FILENAME} -d
# ... then rewrite it internally and stop further processing:
RewriteRule projects/([^/]+)(/?)$ index.php?dir=$1 [QSA,L]

And now two hints:

Please try to use the RewriteLog directive: it helps you to track down such problems:

# Trace:
# (!) file gets big quickly, remove in prod environments:
RewriteLog "/web/logs/mywebsite.rewrite.log"
RewriteLogLevel 9
RewriteEngine On
