After upgrading one of our systems that is running on a cellular modem from 3.5 to 3.7 we have had some issues on the initial connection due to the pre-caching in the serviceWorker. Eventually several things will usually time out and some of our users are unable to load the site due to the number of requests and data transfer .

Our UI does not need many of the pre-cached items, so I have tested using a custom pre-cache manifest. I have tested both an empty manifest, and a manifest with our UI's custom modules and content.

So far in testing I have not noticed any issues, and the initial page load is nearly 1/6 the size it was before.

Are there any foreseeable issues with using a custom pre-cache manifest, or are there Mango or vendor modules that may not be obvious but should likely be pre-cached?

Great, thank you. Changing the name to include the _en and putting it into the overrides/classes directory worked perfectly.

I can confirm that I am restarting Mango after copying the file. I tried using the {MANGO}/overrides/web/modules/mangoUI/classes/i18n.properties again to check and still no luck. I copied the original back to the main location and the modified file to that path and after restarting all of the default strings are back.

I have several files within the {MANGO}/overrides/web/modules/mangoUI/web directory which are loaded and working fine, but it seems that the module's classes directory isn't using the overrides.

I'm using Mango 3.7.7 and I'm wondering if there is a way to override a module's i18n.properties files? For example the file:

{MANGO}/web/modules/mangoUI/classes/i18n.properties

I've tried placing the modified file in several different locations within the overrides folder, and also just concatenating it to my existing core i18n.properties override file.

So far the only way I've gotten it to work is by replacing the actual file within the module, which will be overwritten during any updates.

These are the paths I have tried:
{MANGO}/overrides/web/modules/mangoUI/classes/
{MANGO}/overrides/web/modules/mangoUI/properties/
{MANGO}/overrides/properties/
