I tried to follow the WPMU to optimise browser caching by setting the exoiry to 8 days by adding the generated code into the http section of the NGINX.conf.
I could not find this file on my server. so contacted Siteground, my server host, and received the reply below.
Your directions are to contact WPMU support if there are any difficullties. I would classify this as a difficulty. What do you suggest?
I already use the caching that Siteground suggest, but I dont think these are to do with browser caching, but server caching.
Presumably this will be a common issue and showstopper with shared server services?
Response from Siteground:
Thank you for contacting our help desk.
Unfortunately, due to the nature of shared severs, the nginx.conf file cannot be modified. That way we can preserve the stability and security of the server and therefore the stability and security of all the clients on the server.
If you would like to improve browser caching, you should consider making use of Leverage browsing caching.
You should also consider using our SuperCacher tool: cPanel > SuperCacher > Level 1 Static Cache > ON
To enable our SuperCacher's Level 2 Dynamic Caching you will have to install a plugin on each of your applications first:
After you install the pluigin and activate it via your WP Dashboard, go to your cPanel > SuperCacher > Level 2: Dynamic Cache and turn on the cacher there (for all websites) as well.
You can learn more about our SuperCache tool here:
We also have a comprehensive article on how to reduce account executions overall:
