"Invalid URL syntax"

Hi,

I'm new to the "Squid" world. I'm evaluating this products, seems great!
But... I've a strange problem. I read that some problems may occur with
"non standard" URL (with "_") but in my case it's different:

Every URL is refused by Squid! Ex:

http://www.euronet.be/ returns:

-----
ERROR

The requested URL could not be retrieved

Whiel trying to retrieve the URL: /
Invalid URL syntax
-----

or www.euronet.be/fr return: /fr/ => Invalid URL syntax

Heeeeelp!
