I am currently writing a website in nothing more than HTML and CSS for a client. This client had very few needs, just a few pages to display info, and they wanted to be able to edit the website easily themselves, so I immediately think "Weebly!" Well, this turns out to be a bad idea, as my client is now requesting a forum directly on their site. I don't have access to ASP.NET, which I would normally use in this situation, nor can I use PHP or anything of that nature, and of course my Silverlight is taken away (as that runs user-side). So, my first thought was to set up a Conforums (www.conforums.com) forum and put it in my client's site via an Iframe. This turns out not to work out so well as the user is logged out every time they click on a link in the forum (from the Iframe). So, my question is, without using modern-age methods such as PHP, ASP.NET or the like (straight-up HTML, CSS, Javascript), how can I embed my Conforums forum (or, for that matter, any external website) on my client's site without their users being logged out every time they click a link on the forum?
With all due respect, I don't ever recommend this approach. It's largely frowned upon as it consumes bandwidth traffic that someone else is paying for. If the forum is absolutely necessary I would simply link to it.
