the admins about Last-Modified header violations rather than trying
to interpret datestrings (like the ones not in GMT).

I also added explicit comments to summarize the current assumptions,
so it will be easier for somebody in the future to modify the code.

The following use cases are covered:
1) (F)CGI backend sends a Last-Modified header not in GMT and considered in the future by httpd (like now() in the EU/Paris timezone)
2) (F)CGI backend sends a Last-Modified header not in GMT and not considered in the future by httpd (like now() + 2 hours in the PST timezone)
3) (F)CGI backend sends a Last-Modified header in GMT but with a datetime in the future

Suggestions and opinion are really welcome.

to the default behavior, after discussion with fielding et al about the
purpose of section 3.5. Update the documentation to clarify this.

This patch removes whitespace considerations from the Strict|Unsafe toggle
and consolidates them all in the StrictWhitespace|UnsafeWhitespace toggle.

Added a bunch of logic comments to read_request_line parsing.

Dropped the badwhitespace list for an all-or-nothing toggle in rrl.

Leading space before the method is optimized to be evaluated only once.

Toggled the request from HTTP/0.9 to HTTP/1.0 for more BAD_REQUEST cases.

Moved s/[\n\v\f\r]/ / cleanup logic earlier in the cycle, to operate on
each individual line read, and catch bad whitespace errors earlier.
This changes the obs-fold to more efficiently condense whitespace and
forces concatinatination with a single SP, always. Overrides are not
necessary since obs-fold is clearly deprecated.

The how-to was a little behind the times. Update to modern ciphersuite
selections, and teach the reader more about *why* certain selections and

"last-reviewed" date and pointing to Mozilla's recommendation tool.

if we identified any other parsing errors and handle all 0.9 request
errors as 400 BAD REQUEST, presuming HTTP/1.0 to deliver the error details.
Do not report 0.9 issues as 505 INVALID PROTOCOL because the client apparently
specified no protocol, and 505 post-dates the simple HTTP request mechanism.

As we have removed the possibility to re-use used scoreboard slots in r1757031,
we don't need this check anymore.

This causes inconsistent data in the scoreboard (due to async
connections) and makes it difficult to determine what is going on.
Therefore it is not a useful fix for the scoreboard-full issues (PR
53555).

The consent on the dev list is that we should allocate/use more
scoreboard entries instead.
