Let’s say you have a WordPress blog on `http://=DOMAIN=`, and you want to serve your Discourse forums (which run on a different server) from `http://=DOMAIN==PATH=`. How do you do that?

* * *

**Note** : _This won’t work for serving multiple Discourse instances from different folders on the same domain. You need to use different subdomains so that each site can have different cookies._

* * *

You’re going to need to send all traffic for the domain to one place that can route traffic to the correct server. In this how-to, I’ll use [Fastly](https://www.fastly.com/). So, Discourse will be running on one server, and the other parts of your site (like WordPress) will run on one or more other servers.

## Docker container changes

[First, follow the instructions here to serve Discourse from a subfolder](https://meta.discourse.org/t/subfolder-support-with-docker/30507).

## Fastly

Now to setup Fastly to send traffic to the right place based on the path. I’ll assume that Discourse is being served from `=PATH=`.

Create a new service pointing to your main website and follow the instructions for updating your DNS settings.

Go to the service and click “Configure”. Make sure you have selected Version 2 so that you can make changes. Version 1 is the currently active version and can’t be changed.

In the “Hosts” section, add your Discourse server as a second backend.

In the Settings tab, add a new entry under Request Settings named “Discourse Pass” with action “Pass”.

Finally, for each host edit the conditions to specify where to route traffic.

For your main website, non-Discourse URLs should match.

```plaintext
req.url !~ "^=PATH="

```

For the Discourse host, `=PATH=` URLs should match.

```plaintext
req.url ~ "^=PATH="

```
