Help: Using a GET param in a header link URL...

[GEngle]

Hello,

I'm new to vB but I've scoured many topics/documentation and I can't get this to work.

The header for my forum comes from a remote site and is inserted as an <iframe>. The src of the iFrame is passed in from the remote site such as "http://mysite.com". This all works great for the homepage; however, once you click on any link within the forum the GET param is gone (since it wasn't submitted in the link) and the header goes with it.

Naturally I need to store the domainURL ("http://mysite.com") as a variable that stays around after the initial GET is captured. To this end I created a global variable and initialized it within a Plugin (global_start hook).

Again this works initially (so I know the value is getting set) but it doesn't keep its value past the first page!

Here is my template header code:

<iframe 
  src="$GLOBALS[domainURL]/jsp/Header.jsp">
</iframe>

Here is my plug-in code:

PHP Code:

if ($GLOBALS['domainURL'] == '')
{
  $GLOBALS['domainURL'] = $_GET[domain];
} 


I have even tried storing the GET param in $vbulletin->input->clean_gpc('g', 'domain', TYPE_STR). When I use this I only get Array['domain'] passed back. Perhaps I'm missing something there.

Any help would be appreciated!

Thanks!
