Application suffers with sources index file needing authentication

[mvanbrab]

Observation:

On a query with sources from index file: first login with a user with insufficient permissions (in the test data below textile_user1), index file can't be read, resulting in no results (OK).

But when logging out and logging in with a new user with sufficient permissions (in the test data below textile_user6), the index file isn't read again, resulting in still no results (not OK this time).

Same story when first not logging in and executing the query, followed by logging in with a user with sufficient permissions.

Test data

• a config file (put in ./src) config.json
• associated queries (rename *.txt to *.rq and put in ./public/queries) electronics_products.txt electronics_rare_earth.txt electronics_REACH.txt electronics_recycled.txt electronics_resilience.txt spo.txt textile_disassembly.txt textile_matter_composition.txt textile_product_composition.txt textile_products.txt
• a source index file query (rename *.txt to *.rq and put in ./public/queries/sourceQueries) seeAlso.txt
• the online pods containing the data assumed in the sources in above queries (see @elsdvlee)

These are the involved users:

Note: in the next table, X stands for a positive integer number. As many actors exist as needed per use case.

I solved the problem, but it was not due to caching. It was due to an authentication problem for the index source
