Troubleshoot Firewall Caching Behaviour

Who is this article for?
This article is for Square users using a firewall in conjunction with Square Online Store. This article discusses firewall caching configuration, how to check your configuration and how to change your configuration.

Getting complaints about your online store can be stressful. If you are using a firewall in conjunction with your Square Online Store and your customers complain about seeing out-of-date or old store content, then your firewall may be misconfigured.

You can opt to use a firewall to improve their online store performance. However, caching behaviour is a must consideration when using a firewall. Much like browser cache a firewall can cache (store) web content and this caching behaviour is configurable.

A firewall can be configured to always store web content. This type of cache behaviour is useful for static websites i.e. a website where the content does not change. However, the Square Online Store is a dynamic site and as a result uses HTTP cache headers to indicate which content can be cached.

Before you begin

  • Confirm you are using a firewall in conjunction with your Square Online Store.

  • Connect with your firewall administrator to obtain the firewall caching configuration.

Note: Because firewalls come in different forms and are provided by many vendors, this help article provides general guidance but does not include specific instructions for diagnosing and configuring your firewall. Ultimately, please discuss cache behaviour with your firewall administrator.

Next Steps

Step one: Review and select your firewall configuration

  1. After you’ve obtained your firewall configuration look for a section that refers to “cache options” or “caching options.”

  2. Select the caching option that respects HTTP caching headers. This option may also be referred to as “standard caching.” Stay away from the “cache everything” option.

Step two: Change your firewall configuration

1. Work with your firewall administrator to make the configuration change.

Suggestions for planning the configuration change:

  • Perform the change operation after hours or during an off-peak period.

  • Test your Square Online Store with multiple accounts to ensure the store is operating normally.
