[users@httpd] RewriteRule, [P] and space on URL
I asked about this two weeks ago. Anyone got ideas? If not, who is right
person to contact? Maintainer of mod_proxy or mod_rewrite?
See http://www.uskonnonvapaus.fi/apache-bug/3/one%20two
There is per-directory .htaccess that says
RewriteRule ^(.+)$ http://www.uskonnonvapaus.fi/apache-bug/1/foo.php?q=$1 [P]
and this gives $1 only part to first space. However, on
http://www.uskonnonvapaus.fi/apache-bug/2/one%20two
there is
RewriteRule ^(.+)$ http://www.uskonnonvapaus.fi/apache-bug/1/foo.php?q=$1 [R]
and it works. So it seems that when using [P] -directive and rewriting URL that
contains space there is some bug. Or is this only feature, or should I do
something special to get this working?

The documentation for your version (whatever that is) is included
in the download and build of your version. If you or your sysop
haven't removed it, go to http://localhost/manual/
The documentation at apache.org gets updated as and when the
software itself is updated.

2.2.6 is the latest version I can find on
http://httpd.apache.org/download.cgi, which makes me wonder why the
documentation includes stuff that doesn't even exist in a stable release
yet...

Duh. Debian has only 2.2.6 even in unstable.

I have googled and found that others have same problem. However I have not
found just right solution - only workarounds like "use underscore and not
space" etc.

[B] was new in 2.2.7.

And using RewriteRules from .htaccess is insanely complicated!
Your problem is one I've seen described before, but I don't
recollect the outcome. Maybe google would know.

What happens if you add [B] to the [P] rule?
From the mod_rewrite documentation:
"
'B' (escape backreferences)
Apache has to unescape URLs before mapping them, so backreferences
will be unescaped at the time they are applied. Using the B flag,
non-alphanumeric characters in backreferences will be escaped. For
example, consider the rule:
RewriteRule ^(.*)$ index.php?show=$1
This will map /C++ to index.php?show=C++. But it will also map
/C%2b%2b to index.php?show=C++, because the %2b has been unescaped.
With the B flag, it will instead map to index.php?show=>/C%2b%2b.
This escaping is particularly necessary in a proxy situation, when the
backend may break if presented with an unescaped URL.
