We have a site, which has a main site served by Google Sites and a custom made forum running on a dedicated server. Now we want to use the header from Google Sites also on the forum, so it feels like the same site. I first tried creating an IFrame on the main site and placing the forum inside this IFrame. This looked nice, but I did not find a way to make direct links. The URL always was Open-Org.com no matter which topic on the forum one clicked at.
I have thought about simply copying the relevant HTML code, but this means that I have to recopy it every time the header on the main page changes. Is there a nicer way to do such a thing? It must be a problem that many sites needs to solve.
If what I am describing is unclear, there are more specific information here.
