Re: ISMAP vs browser-generated URL

Daniel,

The problem is that you are trying to use the query_string portion of the
URL to do more than it was intended.  The way imagemap is defined, the
QUERY_STRING component of the URL is reserved for sending only the X,Y
coordinates - you may not use QUERY_STRING to send anything else.  The way
around this is to put all of your custom information into PATH_INFO.

Since putting a QUERY_STRING component into the URL explicitly is an error,
it's easy to understand why the Windows and Unix versions of Netscape work
differently - the Unix version checks for this mistake and corrects it,
while the Windows version doesn't.

Hope this helps!
