Re: MOD: Session Cookie

I figured it out.

When $Cookie_Path = ''; is left blank it uses the path that sets it.
So I changed it to $Cookie_Path = '/cgi-bin'; and now it seems to be working. (Still in both Netscape and IE.) Log into one, cookie is set, head over to the other and the door is wide open

If that doesn't help, I would suggest searching for "cookie mod" and viewing the related threads to see what has worked for others.
