Forcing the Netscape Plugin

[User (Legacy)]

When a user comes to my site for the first time, I want to have them 

prompted to get the Plug In when viewing with Netscape 4.08 or higher.  I've 

looked through the SfxCgi.ini and SfxCgiWC.ini files to see how to do this, 

but my changes aren't making a difference on my server.  Am I looking at the 

right files? 

In Netscape, when I view the http://support.softwarefx.com/cfxie/ site, it 

prompts me for the plugin.  When I view my localhost, it generates an image. 

Can anyone direct me on how to set up my server to prompt a user for the 

plugin when coming from a Netscape 4.08 or higher browser?  Thanks.
