Get rid of the 100% table widths, since they don't render well in MSIE.
Add the back in "Module Identifier".
Fix the remaining extra-space problems.

Remove another hack from the server. The add_required_filters function
was required to make sure that the sub request had the correct filters
when we went send the error page. With the new filter insertion logic,
this is no longer necessary.

Bail on computing the amount of bytes in a brigade if any of the buckets
have indeterminate length (e.g., a pipe bucket). Passing an invalid length
into mod_mem_cache can cause it to overflow its cache buffer.
Ensure that net_time filter isn't added on subreqs - we assume that it is
added on !r->main requests. This led to infinite loop/SEGV when dealing
with anything that created a subreq.
(I don't think core_create_req is a good place for adding this filter.)

Adding the same filters over and over again used to be okay, because
we would lose the extra filters. Now, if a filter is added, it is run.
Unfortunately, this can cause an infinite loop, or it can cause request
headers to appear twice. This commit removes two instances in the core
where we were inserting filters for a second and third time. The bug
was that error responses were causing infinite loops.
This also removes the reset_filters function, which did the exact
same thing as add_required_filters. The two functions were both called
in error conditions, which was part of what caused this bug.

If we insert a protocol filter before we insert a request filter, we
must set the r->output_filter to r->proto_output_filter. If we don't,
then as soon as we insert the request filter, the protocol filter will
be removed. This was causing headers to not be sent on some requests.

Classify some of the input filters as the correct types. Previous to
this patch, the type wasn't too important, because all filters were
put on the same list. After this patch, the filter type is very important,
because there are three different types of filters, and they are all treated
differently, namely:
CONNECTION: Filters of this type are valid for the lifetime of this
connection.
PROTOCOL: Filters of this type are valid for the lifetime of this
request from the point of view of the client, this means
that the request is valid from the time that the request
is sent until the time that the response is received.
CONTENT: Filters of this type are valid for the time that this
content is used to satisfy a request. For simple requests,
this is identical to PROTOCOL, but internal redirects
and sub-requests can change the content without ending
the request.
It is important to realize that the three major types above are actually
broken down into smaller groups in the code, to ensure that the ordering
of filters is always correct.

This finishes the mod_dir/mod_negotiation bug. This final part of the
solution ensures that we don't lose filters if they are added later than
we expect. The problem could be seen if a connection filter was added
after a request-based filter was added in the past. The problem was that
the request-based filters pointed to the first filter in the connection
record, so the new connection filter was never called. Now, all filters
are put on their correct filter lists, and we are sure to always update
all pointers when adding a filter.
Ryan Bloom [Sun, 3 Mar 2002 02:15:52 +0000 (02:15 +0000)]
Fix the mod_dir/mod_negotiation bug, where redirects and sub requests
were not getting the correct filters. This is done by creating a location
in the request rec that holds protocol level filters. Protocol level
filters survive for one request, from the time the request is received
from the user to the time the response is sent. r->output_filters now
stores the request level filters, which are only valid for the lifetime
of one request_rec.
This patch works, but it is not complete. The second half of the problem
is that add_any_filter doesn't check where it puts the filters that it
adds, so it is possible for filters to be put on this wrong list, and
for filters to be lost completely during request processing. That half
of the fix will be coming in the next day or so.

next_filter of NULL to any ap_sub_req_lookup*() fn implies the subreq

We don't need transfer_brigade() because we already have macros to do that
for us, and faster. :)
Warning, though: transfer_brigade() was equivalent to APR_BRIGADE_CONCAT(),
and I don't think that was the right behavior for one of the two callers!
I changed that one to use APR_BRIGADE_PREPEND() since by my inspection that
looks like what it should be, but please check me on this.

Give mod_dav the ability to output both standard and customized

back over to the client; and someday it will be needed to return
specific <DAV:> errors as dictated by the DeltaV spec.

namespace, and an error-tag-name. Remove the 'delayed computation'
function and cxt ptrs in this struct; they were never used.

fields.
