Question

OK, I’m pants at rewrite rules in .htaccess files!

My desired scenario is (using the URL http://doma.in/ as an example):

• First check to see if an index.html file exists in the /public sub-dir; if it does, serve it
  • If it did not; serve (rewrite to) index.php

To expand on my example, say we requested the URL http://doma.in/js/foobar.js:

• First check to see if an foobar.js file exists in the /public/js sub-dir; if it does, serve it
  • If it did not; serve (rewrite to) index.php?controller=js%2Ffoobar.js

That would cover static files but I also need URLs like http://doma.in/foo:

• First check to see if an foo file exists in the /public sub-dir; if it does, serve it
  • If it did not; serve (rewrite to) index.php?controller=foo

And a URL http://doma.in/foo/bar:

• We can assume the file foo/bar does not exists in the /public sub-dir as files can’t be named like that.
  • So serve (rewrite to) index.php?controller=foo&action=bar

I’m sure if this complicated (for me) bit is covered then I can work query-strings into the occasion too; so http://doma.in/foo/bar/foo/bar would serve index.php?controller=foo&action=bar&querystring=foo%2Fbar.

I’d also like to make sure that a trailing slash is handled the same as if a trailing slash was omitted, for example: http://doma.in/foo/bar/foo/bar and http://doma.in/foo/bar/foo/bar/

I’ll handle 404s from within my app as if the file did not exist, it would redirect to index.php which does exist – I’m happy with this unless you’ve a better solution 🙂

I really hope all this makes sense as I’ve been looking to find a solution to this scenario all day now and this is all I have:

Options +FollowSymLinks

RewriteEngine on

RewriteBase /

#RewriteBase /prompt-v3/
#RewriteCond %{REQUEST_URI} ^/prompt-v3/(.*)$

RewriteCond $1 !^public
RewriteRule ^(.*)$ public/$1 [R]

The commented-out lines deal with a sub-dir when on a remote host. So far I can redirect to the /public sub-dir if the file exists there and that’s about it.

Thank you everyone for your help!

Options +FollowSymLinks

RewriteEngine on

RewriteBase /
#RewriteBase /sub-dir/
#RewriteCond %{REQUEST_URI} ^/sub-dir/(.*)$

RewriteRule ^index.html$ $1 [L,R=301]

RewriteCond $1 !^public
RewriteCond $1 !^lib
RewriteRule ^(.*)$ public/$1 [L]

RewriteCond $1 ^public/$
RewriteCond %{REQUEST_FILENAME}/index.html !-f
RewriteRule ^(.*)$ lib/bootstrap.php [L]

RewriteCond $1 !^public/$
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond $1 ^public/(.*)$
RewriteRule ^(.*)$ lib/bootstrap.php?path=%1 [L]

This will look for an index.html file in the public directory and if it does not exist rewrite the URL to lib/bootstrap.php. it in fact checks for any request as a static file in the public directory first and deals with canonicalisation too.
