On a server you run, mode A is one rule: the path of your tracking prefix is relayed to us, and the rest of your site does not move. The app gives you the rule filled in with your domain and prefix, then checks that it answers.
Where: nginx.conf → the server block for acme.com
One location block on your prefix, in the server block for your domain: it relays to edge.trymeritt.com with SNI on — without it the TLS handshake fails and every link returns 502 — strips Cookie and Authorization, and does not send the request body.
Where: httpd.conf or .htaccess
One <Location> block in httpd.conf or .htaccess, with ProxyPass and ProxyPassReverse to us, Cookie and Authorization unset, and SSLProxyEngine on. The proxy modules must be enabled, otherwise the rule is ignored.
Where: Caddyfile
One handle block in the Caddyfile: reverse_proxy to us, with the upstream Host header and Cookie and Authorization removed. Caddy handles TLS to us on its own.
Where: haproxy.cfg
An ACL on the path prefix in your frontend that deletes Cookie and Authorization and sends the request to a dedicated backend: verified TLS, SNI to our host.
Where: web.config
One rewrite rule in web.config that sends your prefix to us and blanks the HTTP_COOKIE and HTTP_AUTHORIZATION server variables. The URL Rewrite module must be installed.
Your visitors carry your site's cookies and tokens. Stripping them before the relay makes sure they never reach us.
A segment of your own workspace, never a generic /r/. A rule relaying a path other than the one your links use would look right and track nothing.
Reload the server: nginx -s reload on nginx, apachectl graceful on Apache. Then run the check in the app.
The click sets a first-party cookie on your domain. Your server can bind a customer id to it, and that is the level that survives a change of device.
Automatic through PayPal and Wise, or by bank transfer, Skrill, Revolut or crypto, with the invoice. A transfer that comes back is caught and corrected on both sides.
$0, $49 or $99 a month. Never a percentage of your revenue, your commissions or your transfers.
