How to add home url to excluded_urls?

[PeideAmonNg]

How do we add the home url ("/") i.e. Director::absoluteBaseURL() to excluded_urls in the saml.yml config file?

silverstripe-saml/src/Middleware/SAMLMiddleware.php

Lines 23 to 32 in 70aabc7

	/**
	* @var array A list of URLs to be excluded from processing via this middleware. These URLs are passed through
	* preg_match(), so regular expressions are acceptable. The default URLs include:
	* - Any URL under Security/
	* - Any URL under saml/
	*/
	private static $excluded_urls = [
	'/^Security/i',
	'/^saml/i'
	];

The match is only made on the path of the URL, so does not include the domain.

For example:

SilverStripe\SAML\Middleware\SAMLMiddleware:
  excluded_urls:
    - '^$'

will add an empty string to the match. If your homepage is e.g. home, then that would look more like ^home/?$.
If you want to match any page under home, then you'd leave the $ off the end.
