Edge Security Acceleration (ESA) allows you to enable caching on ports to cache content on specific ports. By default, ESA caches only static requests on the default HTTP or HTTPS port, such as 80 or 443. You can also enable caching on specific non-standard ports to optimize applications and services of various types.
Supported ports
In addition to common HTTP and HTTPS ports, such as 80, 8080, and 443, ESA also allows you to cache content on the following ports:
HTTP ports: 8880, 2052, 2082, 2086, 2095
HTTPS ports: 2053, 2083, 2087, 2096, 8443
Configure custom ports for caching
In the ESA console, choose Websites and click the website name you want to manage.
In the left-side navigation pane, choose .
Click Create Rule, and fill in the Rule Name.
In the If Requests Match... area, specify the conditions for matching incoming requests. For more information about how to configure a rule, see Rules.
In the Bypass Cache section, specify whether to bypass cache. For more information, see Bypass cache.
In the Caching on Ports section, click Configure. In the port list, select one or more ports.

Click OK.
