apache/mod_rewrite: global external RewriteMap

hi ng,

i have the following problem:

i am using an external RewriteMap

RewriteCond %{REQUEST_URI} .html$
RewriteMap rewrite-static prg:/usr/local/bin/rewrite_static
RewriteRule ^/(.*).html$ /${rewrite-static:$1}

to transform static urls into dynamic ones for php.

I am using vhosts (about 500) and would like to use this rewriting in every
vhost.
When I put the above lines in all of my vhost files, apache opens the file
/usr/local/bin/rewrite_static once for every vhost and runs out of memory.
When I put the above lines to my httpd.conf, the rule does not work at all.
Why? do I have to put it in a special section (tried IfModule)?

Or is there any other way to transform a url like

/index,lang,en,id,8.html

into

/index.php?lang=en&id=8

for an unknown number of key/value pairs? (in normal RewriteRules only 4
key/value pairs are allowed, as the max. number of backreferences is $9)

any help or ideas appreciated!!

do you have a RewriteEngine On in the httpd.conf? it should certainly
be possible to have rewrite rules in the main server config.

if the max number of name/value pairs is known:

RewriteEngine On
RewriteRule /([^,\.]+),([^,\.]+),([^,\.]+)(.*) /$1$3?$1=$2 [C,QSA]
RewriteRule /([^,\.]+),([^,\.]+),([^,\.]+)(.*) /$1$3?$1=$2 [C,QSA]
....
RewriteRule /([^,\.]+),([^,\.]+),([^,\.]+)(.*) /$1$3?$1=$2 [C,QSA]
RewriteRule /([^,\.]+),([^,\.]+),([^,\.]+)(.*) /$1$3?$1=$2 [QSA]

RewriteRule (.*)\.html $1.php

each of the above rules takes the first name/value pair and attaches
it to the query string. since it is chained, the next rule pair will
be tried. when all name/value pairs are gobbled up, only index.html
will be left in your example and the regex of the next rule will not
match, therefore breaking out of the sequence. just make shure you've
got enough lines for all your name/value pairs.
brave people may try just one line with [N] or [R] flags to make a
loop instead for a finite but not formerly known number of name/value
pairs, but one easily has an infinite loop which tends to annoy
clients...
