we have ? in a url and ajp converts it to %3F

Question

with the Mod_jk connector we have this in our /etc/apache2/sites-available file:

RewriteRule \/$ /op_ugw/orderportal/home?switchprofile=RecyledPlants [L] This works fine. and www.recycledplants.com will get you to the correct place.

However on Ubuntu 10.04 server we setup ajp instead of mod_jk . so we have

ProxyPass / ajp://10.1.1.1:8009/op_ugw/orderportal/home?switchprofile=RecyledPlants ProxyPassReverse / ajp://10.1.1.1:8009/op_ugw/orderportal/home?switchprofile=RecyledPlants

When I try to get to recycledplants.randrinc.com (url for testing) I get a 404 error and

description: The requested resource (/op_ugw/orderportal/home%3Fswitchprofile=RecyledPlants) is not available.

the ? has been converted to %3F.

Is there a way to stop Apache from converting the ? to %3F.

Hope this makes sense. thanks Ann
