Bug 22542: Force back button to display personal data

Bug 22542: Force back button to display personal data

This is a follow-up of bug 5371

The following command must not return anything:
grep ^output_html_with_http_headers `git grep -l -P "authnotrequired\s*=>\s*0" opac`|grep -v force_no_caching

This must be a test somehwere to prevent further regressions.
