Why is apache not passing Location header from cgi script back to client
I have an existing cgi web app which used to work fine, but whose behaviour has changed.
One of the cgi programs (under certain conditions) returns a Location header, to cause a redirect.
The Location header never reaches the web browser - instead, Apache seems to return the contents of the page the Location header redirects to.
Unfortunately that page contains javascript which uses the query string inside the Location header - but with this new behaviour the query string is empty, because the browser still thinks the location is the original cgi script.
Why has theis behaviour changed, and what can I do to prevent it happening?

Apparently, the key is whether an absolute URL is specified in theLocationheader.

According to this answer, CGI specifies two different types of redirects: internal and external.
Internal redirects (invisible to the browser) are used when you specify a URL without scheme and host (like otherpage.html or /index.html) in the Location header.
External redirects (performed by the browser) are used only when you specify an absolute URL (ie. http://www.example.com/some/other/page). Absolute URLs must start with the scheme (ie. http).
RFC 3875 contains the relevant documentation:
The Location header field is used to specify to the server that the
script is returning a reference to a document rather than an actual
document (see sections 6.2.3 and 6.2.4). It is either an absolute
URI (optionally with a fragment identifier), indicating that the
client is to fetch the referenced document, or a local URI path
(optionally with a query string), indicating that the server is to
fetch the referenced document and return it to the client as the
response.
