Modify nginx config to not cache index.html
- the problem is that the client html page is taken from browser cache (default browser behavior to my knowledge) and redirects to IDP are not performed on this first client html load attempt but only later on successive requests to the opensearch endpoint to fetch the collections. This runs into: CORS error when requesting automatic redirect to the IDP side:
Cross Origin Resource Sharing error: MissingAllowOriginHeader.
- update cache-control headers to never cache index.html file
