Passing baseHTMLJInitiator in a URL instead of in formsweb.cfg

Question

We are currently trying to dynamically construct a url to run forms with either JInitiator or the Sun Java Plugin depending upon which broswer is being used (ie6 or ie8).
We can detect which browser is being used using javascript and then attempting to append '&baseHTMLJInitiator=webutiljpi.htm' or '&baseHTMLJInitiator=webutiljinii.htm' to the URL depending on the browser version.
Is this possible?
For example we are trying this:
http://<server_name>:<port>/forms/frmservlet?config="+config+runtime
Where +config is a particular config in our formsweb.cfg and +runtime is either &baseHTMLJInitiator=webutiljpi.htm or &baseHTMLJInitiator=webutiljinii.htm
e.g.
IE6 http://<server_name>:<port>/forms/frmservlet?config=browser_test&baseHTMLJInitiator=webutiljinii.htm
IE8 http://<server_name>:<port>/forms/frmservlet?config=browser_test&baseHTMLJInitiator=webutiljpi.htm
We can get this working by duplicating the configs in our formsweb.cfg file i.e. specifying the baseHTMLJInitiator param in formsweb.cfg rather than in the url.
So we can run the following config if using IE6:
[browser_test_jini]
baseHTMLJInitiator=webutiljini.htm
etc.
and this config if running IE8
[browser_test_jpi]
baseHTMLJInitiator=webutiljpi.htm
etc.
This works but we were hoping to avoid duplicating the config definitions in our formsweb.cfg file.
Thanks in advance for any info.

thanks but as I said in my original post, we have got it working using multiple configs but we have many environments and we wanted to avoid having duplicate entries for every environment.
While I understand there are other files such as frmall.jar, we can get it to work correctly by putting all params in the common section except for baseHTMLJInitiator.
So the following URL will run the session in the Sun JPI:
http://<server_name>:<port>/forms/frmservlet?config=browser_test_jini
using the config:
[browser_test_jpi]
baseHTMLJInitiator=webutiljpi.htm
While http://<server_name>:<port>/forms/frmservlet?config=browser_test_jini runs in JInitiator using the following config:
[browser_test_jini]
baseHTMLJInitiator=webutiljini.htm
All other params are set in the common section of our formsweb.cfg file.
So why can't we just pass this single parameter through the URL?
