Re: RewriteRule, [P] and space on URL

Quoting Jori Mantysalo <Jori.Mantysalo@xxxxxx>:

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?

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.
