In mass hosting setups (using mod_vhost_alias or mod_rewrite) where
the hostname is interpolated into the filename, we need to be sure
that the result of interpolation doesn't expose parts of the
filesystem that should be private. This was done by checking the
syntax of the Host: header according to RFC 1123 and RFC 952. However,
many people have broken configurations that violate this syntax
(frequently because they use underscores in their names), and it also
doesn't accommodate the current effort to internationalize the DNS. I
don't think the former is a compelling reason to relax the syntax
checking, but the latter does justify this change.
The only RFC on internationalized DNS at the moment is RFC 2825 which
is an introduction to how difficult the whole thing is; the other
official documentation is a pile of Internet Drafts produced by the
Internationalized Domain Names Working Group of the IETF (with names
starting "draft-ietf-idn-"). However they have very little to say
about URIs, and the current Internet draft about internationalized
URIs (draft-masinter-url-i18n-05) has very little to say about
hostnames :-( On the gripping hand there is some useful information at
<http://www.apng.org/idns/> where there is some iDNS testbed work
going on. The basic idea is that although the format of the hostnames
in the DNS itself remains compatible with RFC 1123, the actual
hostname presented to the resolver is in UTF8, and therefore the
hostname in the URL and Host: header is also in UTF8.
This change relaxes the checking so that only character sequences that
are sensitive to the filesystem are rejected, i.e. forward slashes,
backward slashes, and sequences of more than one dot.

Remove MMAP handling from the default handler. MMAPs are created by the
file_bucket read function now. If we try to read from a file bucket and
it makes sense to convert that bucket to an MMAP, that just happens.
Per new-httpd discussions, this version of mod_autoindex has been set
aside as a test for rputs style backwards compatibility. It has really
horrid chunking charateristics, so it was the ideal nominee for the job.
Please refer to src/modules/standard/mod_autoindex.c for the complete
revision history. When rputs is entirely eliminated (if it ever is)
then this version should be eliminated.

The content-length filter needs to compute the length even if the

the content-length has changed because some other filter changed the

The byte-ranges filter. This looks like it should work, but the
Acrobat plug-in doesn't like it for some reason. This does work better
than what we currently have, because at least it returns all of the
requested data. This basically removes all BUFFs from the byte-range
code and removes all of the byte-range code from the default-handler.
Byte-ranges are now handled by a filter, which makes sense, and it allows
us to handle byte-ranges for all requests, not just files.

Convert a lot of apr_ssize_t to apr_size_t. We don't ever accept or return
signed values in these integers, and we return the error codes directly,
so we should always report the number of bytes read/written correctly. If
we have an error, that is 0 bytes. If that is true, then using signed

Always compute the content-length regardless of whether it is sent to the

Remvoe AP_END_OF_BRIGADE. This definition didn't really mean anything,
because it didn't signify the end of the brigade, and it didn't signify
the end of a response. It ended up meaning flush the data, which can be
detemined with bucket type checks. This also makes the FLUSH and EOS
buckets have a 0 length, which makes a lot of code cleaner, because now we
can just add lengths and be sure they are all >=0.

ap_send_fd should not be sending an EOS bucket, so we should remove any
trace of that possibility from the code. First of all, there is nothing
that says you can only send one file bucket in a response, and second,
even if a handler sends a file, nothing says that it can't add text before
or after it too.

Allow the core_output_filter to save data in the filter past the end of
the first request if this is a keepalive connection. This allows us to
save the end of the first request until we have enough data from the
second request to make it worthwhile to send the responses. In order
to do this, we need to allocate mmap's from the connection pool instead
of the request pool. If we don't use the connection pool, then the mmap
is freed before the data is sent, because the mmap is freed at the end of
the first request.

Change the content-length filter to give up (i.e., not provide content-length)

response to the client immediately.
