I'm having this problem on a site I am developing.<BR><BR>If you register yourself, look round round the site, close your browser and open a new browser and go to the site again you get the following error message. If you delete the cookie for the site it works again.<BR><BR>Response object error 'ASP 0156 : 80004005' <BR>Header Error <BR>?<BR>The HTTP headers are already written to the client browser. Any HTTP header modifications must be made before writing page content. <BR><BR>Any idea what is causing this? It is not giving me a page so I am not sure where to look in fixing it. Would this come from the index.asp page it's trying to land on?
