mod_rewrite: periods from URI gone in the query string

Question

Problem: See examples below. When using mod_rewrite to put "the URI part after the script name" into the query string (in any way), the ending periods (.) of every "directory" are removed. (Apache 2.2.14 on win32.)

Question: Is there any way to solve this or do I have to parse REQUEST_URI?

Try to get the value from THE_REQUEST instead:

RewriteCond %{THE_REQUEST} ^[A-Z]+\ /simp\.fcgi/([^?\ ]*)
RewriteRule ^simp\.fcgi/ simple.fcgi?qs=%1 [QSA]
