Linux infong1 2.0.36 #1 Wed Mar 24 21:40:07 MET 1999 i686 unknown
gcc version egcs-2.91.60 19981201 (egcs-1.1.1 release) 
>Description:
passing a URL to the rewriteprog wich contains %0A in fact 
passes 2 lines to the rewriteprog. Because of the recommeded 
structure of the rewriteprog (one line in, one line out)
the apache gets back two lines wich is very confusing for it.
>How-To-Repeat:
Install a {prg:/my/rewriteprog} and pass a url containing
%0A to it.
>Fix:
A workaround is to prepend a magic string to the url.
If the rewriteprg cannot find the magic string at the begin of a
inputline it should produce no output
