I've got some backlinks coming to me now that seem to be doing some sort of urlencoding of the entire link. So the request which should look like
Code:
/mypage.php?query=somequery
is being encoded as
Code:
/mypage.php%3Fquery%3Dsomequery
and of course Apache throws a 404 error. I'm sure there's an easy way to deal with this (mod_rewrite probably, but I can never figure out how to work it).
