Description Alexey Vlasov 2008-12-21 10:32:47 UTC 
Proxy request:

On server1 -
# cat .htaccess
RewriteEngine On
RewriteRule (AAA.*) http://server2.com/phpinfo.php?q=$1 [L,P]

# telnet server1.com 80
GET /AAA%20AAA HTTP/1.1
HOST:server1.com

answer from server2:
QUERY_STRING    q=AAA
REQUEST_URI     /phpinfo.php?q=AAA
SCRIPT_NAME     /phpinfo.php

Usual requst:
# cat .htaccess
RewriteEngine On
RewriteRule (AAA.*) /phpinfo.php?q=$1 [L]

Similar request but the answer is:
QUERY_STRING    q=AAA AAA
REQUEST_URI     /AAA%20AAA
SCRIPT_NAME     /phpinfo.php

By the way this patch didn't solve that problem I described first. You should add the following:
