Bug ID: 11581
Summary: HTTP 404s generated badly in some cases
Change sponsored?: ---
Product: Koha
Version: master
Hardware: All
OS: All
Status: NEW
Severity: minor
Priority: P5 - low
Component: Architecture, internals, and plumbing

There are several scripts that do the following when they want to signal that a
resource (usually a MARC record) does not exist:
print $query->redirect("/cgi-bin/koha/errors/404.pl");
This is not great, because what actually happens is that an HTTP 302 redirect
is issued, followed by the 404. This wastes a bit of time for the user agent,
and might be problematic if you let search engines crawl your OPAC.
Better would be doing
print $cgi->header( -status => '404 record not found');
or if a more specific message should be displayed, constructing it and calling
output_with_http_headers $query, $cookie, $error_template->output, 'html',
'404 Not Found';
The affected scripts are:
catalogue/showmarc.pl
opac/opac-ISBDdetail.pl
opac/opac-MARCdetail.pl
opac/opac-authoritiesdetail.pl
opac/opac-detail.pl
opac/opac-export.pl
opac/opac-showmarc.pl
opac/opac-topissues.pl
opac/tracklinks.pl
