I would still like a couple features, but don't have the time to
code them myself. These are easy additions for people who are used
to working on these parts of the server:
1) The ability to set the Cache-Control header by directory/location/file
This could be done like mod_expires, but we may be better served by
a general directive, a la
HeaderSet <field-name> <field-content...>
HeaderAppend <field-name> <field-content...>
HeaderRemove <field-name>
as an alternative to the cern_meta mechanism.
2) The ability to send 410 Gone via mod_rewrite or mod_alias.
It is just another form of redirect. Actually, I would prefer
that mod_rewrite be able to send *any* status code by internal
redirection to the response content and a [nnn] at the end of
the rule indicating the final status.
These fall under the category of "why HTTP/1.1 is better than HTTP/1.0"
and thus would be big selling points.

it's still in my to-go-through queue. I wouldn't mind if Apache 1.2 was able
to handle all NCSA auth-directives, if it can be logically reconciled.

For what it's worth, I tested this at the time and I think it should both
be committed.

Whatever happened to my patch that added TAKE12, NCSA-style auth
directives, and the ability to have a command handler decline? I
thought it was kinda useful (even without the NCSA-compat stuff).

+1 on adding TAKE23 to http_config.c.

I've put together a module which implements header setting/removing. It
is called mod_headers.c, add I've uploaded it by ftp to hyperreal.com in
httpd/incoming/mod_headers.c.
It adds a new directive, Header, which can be used to add, append or
remove HTTP headers, e.g.
Header set Cache-Control: max-age=84000
Header append Connection: some-new-thing
Header set Author "John D. Doe"
Header unset MyBadHeader
The directives can be given for the main server, virtual servers, in
<Directory> sections/.htaccess files, <Location> sections and <Files>
sections. They are applied in that order (so .htacess files can override
settings in main or virtual server configs). The headers are always
merged, so that anything set in (say) the main server config always
applies, even if other more Header directives are given in a virtual host.
Of course, for example, the virtual host can remove a header set in the
main server with Header unset.
It could be used to set a header for all files in a directory
(via .htaccess) or individual files (with <Files> say):
<Files ~ .*\.gif>
Header set Cache-Control: max-age=84000
</Files>
It operates in the 'fixup' stage of the request, which means it does not
affect headers added during the handler phase (in particular, headers like
Server, Date, Last-Modified, ETag). If any of these are set by a Header
directive, they will be added as a duplicate header during the handler
phase. It might be worth explicitly disallowing the setting of these
headers by Header.
Because Header can take two _or_ three arguments, I've had to update
http_config.[ch] to support a new TAKE23 mode. I'll append this patch
below.
