So, in a "regular" web server one can use mod_rewrite and create something like this:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^([0-9a-zA-Z-]+)/([0-9a-zA-Z-]+)/([0-9a-zA-Z-]+)$ ?menu=$1&action=$2&title=$3
</IfModule>
I tried several different ways to do something in app.yaml, but no success so far. The one that seemed closer is this one:
handler:
- url: /([0-9a-zA-Z-]+)/([0-9a-zA-Z-]+)/([0-9a-zA-Z-]+)$
script: index.php?menu=\1&action=\2&title=\3
However, it gave an error saying that I was trying to require a filename called "index.php?<all_the_url_parameters_here>", which couldn't be found, obviously.
I really need some advice.
