Bug#1019418: apache2: Content-Location header doesn't escape colons

[Peter Chubb <peter.chubb@unsw.edu.au>]

Package: apache2
Version: 2.4.54-1~deb11u1
Severity: normal

Dear Maintainer,

We have an apache2 server that serves URLs of the form:
   https://server.com/a/b/foo:phd.html

The Content-Location HTTP response header returned is then
   Content-Location: foo:phd.html

which is invalid because of the colon.  It should return
   Content-Location: ./foo:phd.html
so that the : is not treated as a protocol delimiter.
