hi... i cannot resolve this yet, but i can see http headers when this problem happens...
for example:
URL:*{color:#000000} http://www.google.com/{color}*
Request: GET http://www.google.com/ HTTP/1.1
Host: www.google.com
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041215 Firefox/1.0 Red Hat/1.0-12.EL4

Response: HTTP/1.x 407 Proxy Authentication Required
Server: Sun-Java-System-Web-Proxy-Server/4.0

Content-Length: 146
Content-Type: text/html
Proxy-Authenticate: Basic realm=""
Connection: close
so...i look in specification about http 1.1 (rfc2068) (if i not wrong), when the server receive a request that needs authentication of the client he response whit a "request" of these autentication, so the client send them...
i think that these response about the server needs that the client need autenticate is in the response with http code 407, but in rfc says that the parameter Proxy-Authenticate are like Proxy-Authenticate: Basic realm="string_here" where "string_here" is a id defined by server.
So.. the string in "realm" ¿should not be diferent from empty (null) ? :(
Thanks in advance :)
