rogue urls

[frances]

Not sure if this is an apace or a php question...

I have a site that effectively used mod_rewrite

But im getting strange urls coming in:

"index.php?section=5%E2%88%8F=88&cat=cat"

They should be

[site.com...]

which are then rewritten on the server to

index.php?section=yy&cat=cat

all urls from the site do seem to work correctly.

If someone could just point me to a method of sanitiising these rogue urls?

And I just dont understand where they might be coming from

thanks

frances,

This recent thread [webmasterworld.com] should help get you started.

Most times, these are caused by coding errors, either on a site that links to you, or in the code of a robot.
