Issues with find.js from in China


We have an Episerver DXC application that is working ok in most geolocations but is failing to serve in China. 

Episerver Support are investigating, but have not yet found a solution to fix the issue, which I suspect is related to "the great firewall". So I wanted to share this with everyone and see if there are any other ways to resolve it.

Version Info

  • Episerver CMS 11.10.6
  • Episerver Commerce 12.15.1
  • Episerver Find 13.0.5

Identifying the issue

We used to test website load times from various geolocations and identified that was failing to load in China.

I'm not aware of many tools around that test China, if you know any others please let me know.

What we have tried so far

Episerver Support recommended we try the following, but unfortunately, it hasn't resolved the issue;

Step-by-step guide


The steps below add a change to the web.config that reduces the number of calls to but the correct version must first be determined.
  1. Determine the version of Find installed on the Web App. Do this by examining the packages.config file (for example, <package id="EPiServer.Find" version="12.7.1" targetFramework="net462" />) or the <assemblyBinding> section in the web.config; for example, the following assemblyBinding indicates that Find is version
    <assemblyIdentity name="EPiServer.Find" publicKeyToken="8fe83dea738b45b7" culture="neutral" />
    <bindingRedirect oldVersion="" newVersion="" />
  2. Add the following line to the configSections area of the web.config:

    <section name="episerver.find.ui" type="EPiServer.Find.UI.FindUIConfiguration, EPiServer.Find.UI" />
  3. Add the following line just prior to the <sysytem.web> section, and include the Find version determined in Step 1 (use the first three version places):

    <episerver.find.ui clientSideResourceBaseUrl="" />
  4. After the changes are deployed, monitor the External services calls to ensure there is a reduction in calls.

What I'm thinking to try next

I'm wondering if we can serve this JS from our domain, rather than the client request it from 

Can anyone recommend this approach?

Many locked down (with no or limited internet access) sites with a find implementation use the approach described in

I.e. hosting the resources (js/css) on the site domain and pointing the clientSideResourceBaseUrl here.

Thanks Daniel, that's exactly what I was looking for. I'll follow up / confirm once it's deployed.

Good news, this approach resolved the issue;

You can see in the screenshot below that the JS file is now served in China directly from our own domain rather than from
