OK, there are two server which runs a site. When you are logged in on the site on one of the servers, how would you create a script which alerts the other server, and changes certain html code.
For example, if a person is logged in and goes to a part of the site which runs of the different server, what script could be used so that the different server detects you are logged in and changes html. The html could just be a text which say you are logged in, for example.
