Relay proxy

The Smartlook relay proxy relays HTTP requests from your subdomain to Smartlook's recording domains, allow you to bypass potential browser settings or extensions configured to limit data capture. You will have to have access to your server. If you do not have access to your server, contact your developer.

The Relay Proxy is developed as an open source project. If you are experiencing an issues, be sure that you are using the most recent version of the relay proxy. If the issues persist, go to the Smartlook Relay Proxy GitHub to open an issue, or contact our support.

Installation and deployment

To install and deploy the Smartlook relay proxy:

1. Go to Docker Hub to get the Smartlook relay proxy image.
2. Run the image and configure environment variables to your needs.

   docker run --name="smartlook-relay-proxy" -d \
     # can be also set with "--env-file"
     -e LOGGER_LEVEL=<level> \
     -e MANAGER_HOST=<host> \
     -e WEB_SDK_WRITER_HOST=<host> \
     -e ASSETS_PROXY_HOST=<host> \
     -p <port>:8000 \  # mapping is optional, internally runs on port 8000
     smartlook/relay-proxy:latest
   

3. Create a subdomain and point it to the container. It is best to use a subdomain of your website's domain.
4. Deploy the following script. Be sure to replace any URLs with your own URLs. Do not set region.
   HTML

   <script>
   	window.smartlook ||
   	  (function (d) {
   	  var o = (smartlook = function () {
   	    o.api.push(arguments)
   	  }), h = d.getElementsByTagName('head')[0];
   	  var c = d.createElement('script');
   	  o.api = new Array();
   	  c.async = true;
   	  c.crossOrigin = 'anonymous';
   	  c.type = 'text/javascript';
   	  c.charset = 'utf-8';
   	  c.src = 'https://<your-relay-proxy-host>/recorder.js';
   	  h.appendChild(c);
   	})(document);
   	smartlook('init', <project-key>, { host: '<your-relay-proxy-host>' });
   </script>
   

You have now installed and deployed the Smartlook relay proxy. You can check if the relay proxy is working correctly by seeing requests sent through your subdomain in the Network tab of your browser DevTools.

Environment variables

All variables are optional. The default values are listed in the table:

Regional setup

Smartlook offers two regions for data storage: EU and US. By default, all projects are set to the EU region. To change your data storage region, contact Smartlook Support.

If your project is set to the US data region, you need to set the variables as follows:

If most of your visitors are located in a different region, you can set environment variables to reduce network latency. Smartlook servers are located in four regions:

• EU (Frankfurt)

• South America (São Paulo)
• Asia (Singapore)

To set up for other regions:

South America

Only possible if WEB_SDK_WRITER_HOST is available:
