- The route compiler does not add extra space or line-feed,
- The generated regex does not use the 'x' modified any more,
- The PHP and apache matchers do not need to strip any chars (vs space and line feed before),
- The space characters are escaped according to the apache format
Only + and % are now encoded in generated routes, since they are the only characters that, if not encoded, could cause problems/conflicts when decoded. Namely + turns into a space, and % followed by numbers could do funky things.
The matcher decodes everything which works since nothing will have %NN without being escaped, and + are escaped as well.
The _scheme requirement can be used to force routes to always match one given scheme
and to always be generated with the given scheme.
So, if _scheme is set to https, URL generation will force an absolute URL if the
current scheme is http. And if you request the URL with http, you will be redirected
to the https URL.
