Go live

Describes some typical actions, such as mapping host names in the DNS and restricting edit access, when going live with sites in Optimizely Digital Experience Platform (DXP).

Map domain hostnames (required)

Environments in DXP are accessed using a set of dxcloud-URLs that are set up and verified according to platform requirements. Examples:


Before going live, you must apply and verify the same DNS settings for the domains you intend to use with your DXP. This includes creating an _asuid_record used by Azure and a CDN-verify record to confirm that you own the domain.

Usually, these DNS records are modified:

  • CNAME – Creates an alias for a hostname.
  • A-record – Maps a hostname to an IP address.

The following instructions show how to modify the DNS settings. You can use Microsoft DNS Manager if you host your name servers or the web interface of your DNS service provider. Or, contact your DNS service provider if you are unsure how to change these settings.

Modify the DNS settings



The following steps must be done for each domain with which your application should be associated.

Before going live

  1. Configure your Optimizely Content Management System (CMS) to respond to the incoming hostnames you plan to use, such as www.domain.com. Also, configure some default URLs like hostname using "*" (preferred), or alternatively:


    The appname123-slot.dxcloud.episerver.net address validates the site during deployments.

    Go to CMS > Admin > Configuration > Manage Sitesto map hostnames and URLs.

  2. After you map the hostnames, inform Support about which URLs you will use.

  3. Optimizely sends you an email containing the following:
    a. Verification information for CDN and Azure (cloudflare-verify and awverify, these are standard TXT DNS records).
    b. The A-record pointer is to be used later when going live.

  4. Do the following to verify your ownership of the domain and subdomain for the CDN and in Azure:
    a. CDN. Create a record in your DNS using this format:

    (Optimizely provided the unique numeric value for the TXT record.)

    b. Azure. Create a record in your DNS using this format:

    awverify.SUBDOMAIN.DOMAIN.com IN TXT appname123.azurewebsites.net

    Example: awverify.www.episerver.net IN TXT dxcwebapp.azurewebsites.net



    Verify the settings for Azure and CDN for each domain and/or subdomain to which you want your DXC environment to respond.

  5. When done with the DNS updates, contact Support again to finalize the verification procedure and add your verified domains to the production environment.

When going live

To send traffic from your custom URL to the DXP, you must create CNAME records in your DNS, pointing to the corresponding DXP endpoint.

  1. Update the A-record at domain.com so, it points to the IP number you received in the Optimizely email (see step 3 in the previous procedure).

  2. Add dxcloud.episerver.net to the URL you want to target with CNAME. When this is done, the site is live. Examples:

    • www.DOMAIN.com IN CNAME www.DOMAIN.com.dxcloud.episerver.net
    • www.customer.com IN CNAME www.customer.com.dxcloud.episerver.net
    • beta.client.net IN CNAME beta.client.net.dxcloud.episerver.net
    • prod.company.com IN CNAME prod.company.com.dxcloud.episerver.net
    • country.charity.org IN CNAME country.charity.org.dxcloud.episerver.net

Redirect to secure URLs

HTTPS is the secure version of HTTP, adding encryption to the communication between the browser and the editing environment. Redirect in DXP follows industry standard best practices, redirecting you from a non-secure www URL to a secure www URL through configuration (see below).

The service supports:

  • Redirect of non-secure www URL http://www.domain.com to a secure www URL https://www.domain.com.
  • Redirect of non-secure root domain http://domain.com to www URL http://www.domain.com.

You can add a redirect rule by modifying web.config in your Optimizely solution.

Example: HTTP to HTTPS redirect rule.

<rule name="Redirect to HTTPS" 
<match url=".*" 
  <add input="{HTTPS}" 
       pattern="OFF" />
<action type="Redirect" 

The service does not support the following by default:

  • Using the root domain "domain.com" as the default domain for the site.
  • Redirect of TLS/SSL secured root domain https://domain.com to another URL.



In many cases, this is not needed because it is seldom that a site visitor would manually enter https://domain.com and start by typing https. Rather they would enter domain.com, which redirects to the secure URL at https://www.domain.com as expected.

Restrict log in access (optional)

To ensure that the editing environment is only accessed from approved locations, you can restrict the login to only apply to specified IP addresses on the allow list. See Restrict Environment Access.

Single Page Application considerations

You should set up usage tracking parameters correctly to ensure that the website traffic volume monitoring is correct. For websites using the Single Page Application (SPA) concept, specifically configure the page view tracking because pages on these websites will not reload during usage. See Consumption Metrics for information about configuring page view tracking for single-page applications.
