Ajax vs IE Plugin - parameterised URLs with Excel launch actions

[sarahallen1]

I want to parameterise my URLs so I need to use Ajax for that (selections and bookmarks can't be passed into the URL using the plugin).  But then I have buttons I want to work that open up specific (variable) files in Excel.  When clicked in Ajax, these buttons just open http://servername/QvAJAXZfc/EXCEL.EXE rather than the application path I've specified also with parameters (like below).

The buttons themselves work well in IE Plugin or the desktop client - so I think I've set up the application/directory/parameters etc OK.  But not in Ajax.

An example URL (which works in Ajax but not in IE Plugin):

https://webserver.domain.com/QvAJAXZfc/opendoc.htm?document=ExampleAppName.qvw&host=QVS%40servername...

I'd really like some help with this - any ideas on whether it's possible?  I don't really mind whether I use Ajax or IE Plugin for this, but need to use both features combined!

Thanks v much in advance
