[lillie-dae]

Overview

Jira ticket: https://nhsd-jira.digital.nhs.uk/browse/XXX)](https://nhsd-jira.digital.nhs.uk/browse/PRMP-919

Description

Users are experiencing caching issues on live after investigation nginx config cache control had a 2 year cache on "/*" this was causing index.html to cache the links to the js/css files. (we verified the asset files were getting unique hashes after their names for example '/assets/index-CHePbE5B.js' )

So this solution we resolve the issue we remove cache-control from all routes but leave it on just assets.
