One way is to put code in the global.asax Application_endrequest handler.
See
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnaspnet/html/asp01242002.asp in the section "How Can I Add a Standard Header and Footer to Every Page in My Application?"
I believe this is for aspx pages only. If you want it for html pages, then try "Enable document footer" in the IIS properties for your web site.
