+# goatcounter-forwarder
+
+This is small Go app designed to sit between the Caddy webserver and [Goatcounter](https://github.com/arp242/goatcounter) to record pageviews as they happen.
+
+The `forward_auth` directive is (ab)used to send a copy of each request to goatcounter-forwarder that then extracts all relevant information from the request and enqueues it for submission to a Goatcounter instance.
+
+It's configured with environment variables:
+
+* `GCFWD_HTTP_ADDRESS`: the HTTP address that goatcounter-forwarder should listen on (default `127.0.0.1:7000`)
+* `GCFWD_INSTANCE_ADDR`: the address of the Goatcounter instance to report statistics for (required)
+* `GCFWD_TOKEN`: a Goatcounter API token with pageview reporting access (required)
+
+Once setup and running, it can be added to your Caddy config as so:
+
+```
+forward_auth <goatcounter-forwarder address> {
+    uri /
+}
+```
