Segment length in uri problem

Hi
I've defined a new route as

Code:

$routes->get('/opendata/(:segment)', 'Tools::openData/$1');

This Tools/openData controller/fuction receives 1 parameter, which is a base64 encoded string of about (average) 500 characters

I've tried with

Code:

https://myApp.com/opendata/dGhpc2lzanVzdGF0ZXN0dGhpc2lzanVzdGF0ZXN0dGhpc2lzanVzdGF0ZXN0dGhpc2lzanVzdGF0ZXN0dGhpc2lzanVzdGF0ZXN0dGhpc2lzanVzdGF0ZXN0

120 characters approx and everything works fine.

Now, I've tried with a real world example which is about 500 char. long and I get a 404 error

1. Any workaround or config setting to allow this ?

2. Any function that could shorten/compress this string (without database, cookies, etc.) univocally so it can work without modifying anything else?

Thanks a lot
