Please little help to rewrite the URL

Hi all,
can anybody help me to set up a rewrite rule like this:
I need to scan the request and replace all the request with

parameter=null
with
parameter=

for example
http://server/path/mycgi?param1=null&param2=b

should be translated to:
http://server/path/mycgi?param1=&param2=b

Please help!
Thanks
Laura
