+gahhhhhh this was driving me crazy, putting it here so i don't lose it
+
+basically this solves the problem where you have pages like 
+
+```
+http://example.com/page2/index.php?query=true
+``` 
+
+and you want it to display in the browser as the much nicer
+
+```
+http://example.com/page2?query=true
+```
+
+and you can't use nginx try_files because you promised yourself you were gonna make this work in apache "for old times' sake"
+
+basically: this takes a surprisingly large number of rewrite rules. in order:
+
+- remove trailing slashes, `page2/` -> `page2`
+- remove file extensions, `page2.php` -> `page2`
+- remove index filenames, `page2/index.php` -> `page2`
+- oh yeah for EACH of those last three things, I hope you remembered to preserve the query string, so `page2/?query=true` -> `page2?query=true`
+- okay now you have a nice short URL in the browser. now just undo all that logic to get the actual php file to run on the server.
+- if `page2` is a directory then serve from `page2/index.php`
+- if `page2.php` exists then serve from `page2.php`
+- if none of those things exist then fall back on static file hosting. like, `page2.html` might exist, you can serve that, sure, why not.
+- oh you wanted to remove the html extension too? okay do all that again bozo.
+
+```sh
+RewriteEngine On
+#LogLevel alert rewrite:trace6
+
+# remove trailing slash
+RewriteRule (\/.*)\/+(\?.*)?$ $1$2 [R]
+
+# remove file extensions
+RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -f
+RewriteRule (.*)\.(php|html)(\?.*)?$ $1$3 [NC,R]
+
+# remove index.php index.html etc
+RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-d
+RewriteRule (.*)\/index(\?.*)?$ $1$2 [NC,R]
+
+# serve php file
+RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI}.php -f
+RewriteRule (\?.*)?$ fcgi://php:9000/usr/local/apache2/htdocs/%{REQUEST_URI}.php$1 [P,L]
+
+# serve php file with index
+RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI}/ -d
+RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI}/index.php -f
+RewriteRule (\?.*)?$ fcgi://php:9000/usr/local/apache2/htdocs/%{REQUEST_URI}/index.php$1 [P,L]
+
+# serve html file
+RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI}.html -f
+RewriteRule ([^?]*)(\?.*)?$ $1.html$2 [L]
+
+# serve html file with index
+RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI}/ -d
+RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI}/index.html -f
+RewriteRule ([^?]*)(\?.*)?$ $1/index.html$2 [L]
+```
+
+some useful tricks:
+- [NC] can be added after any regex rule to make it Non-Case sensitive.
+- [R] means "in-browser redirect" and is used when you want to fix a URI on the user's side. if you don't do this then it only affects where the server pulls data from.
+- [P] means "proxy" and it allows you to have the server pull data from another machine or from a program running on a local port.
+- [L] means "last one" and it skips all remaining rewrite rules, in case you were worried about matching too many of them.
+
+all this and more can be found at [the apache2 docs](https://httpd.apache.org/docs/current/mod/mod_rewrite.html).
+
+if there's an easy way to do all this then please please tell me, I miss try_files so much, holy cow.
