502 apache proxy error with IE! ARGH!

Accessing my site in IE gives a 502 proxy error when accessing: /
test.php?ID="18"
It appears that the double quotes are handled differently, and the
servers behind the load balancer choke when they get a back slash,
complaining of a malformed http request.

Is there some way to undo what IE does to the query string via rewrite
or some such?

I've been at this all day, please save me before it's too late.


from access.log:
Firefox/Mac:
"GET /test.php?ID=%2218%22 HTTP/1.1" 200 506 "-" "Mozilla/5.0

IE/Win:

Quotes are not valid in a URL which is why the firefox turns them into %22.
I'd suggest you change your site so that the URLs it uses follow the RFC
http://www.ietf.org/rfc/rfc1738.txt
