Has anyone had experiences where mod_headers
directives often fail to have any
effect?
- It is unable to modify headers, only create &
modify newly added headers.
Within my .htaccess file I carried out the
following simple tests.
1)
Header always set MyCustomHeader
myCustomValue
-- this works fine
Header always set MyCustomHeader2
unsetMe
Header always unset
MycustomHeader2
-- works as expected - the header is not in the
response 2)
Header always set Cache-Control
max-age=33
-- this works ONLY if apache
doesnt normally include a Cach-Control header of its own
accord.
3)
Header always set Cache-Control
max-age=33
Header always unset Cache-Control
-- as with 2), this works ONLY if apache hasnt
already added such a header
It seems
that mod_headers cannot operate on *existing*
headers! - Only on headers generated by itself!
I have searched through various bug lists,
archives, documentation etc.. but to no avail.
NB, I have used the 'always' condition keyword to
ensure all header tables are used. Without this keyword, the tet results are the
same.
Environment:
Linux, Fedora Core

httpd 2.2.2
