Server config in README: Exceptions from cache retrieval for dynamic requests

[lukasbestle]

From #26:

# don't serve for active sessions
RewriteCond %{HTTP_COOKIE} !kirby_session
# don't serve for URLs with query string
RewriteCond %{QUERY_STRING} ^$
# don't serve for URLs with Kirby param(s)
RewriteCond %{REQUEST_FILENAME} !:

We need to find equivalents for nginx, Caddy and the PHP loader.

AI suggestions as a rough starting point. Don't trust.

Nginx

# don't serve for active sessions
if ($http_cookie ~* "kirby_session") {
	break;
}

# don't serve for URLs with query string
if ($query_string != "") {
	break;
}

# don't serve for URLs with Kirby param(s)
if ($request_filename ~ ":") {
	break;
}

Caddy

@no_cache {
	# don't serve if there IS a kirby_session cookie
	not header_regexp Cookie kirby_session
	# only serve if query string is empty
	not query *
	# don't serve if filename contains colon
	not path_regexp .*:.*
}

# Use this matcher in your route where needed, for example:
handle @no_cache {
	# your caching or serving logic here
}
