Application Integratior problem

Hi,

I had integrated the yahoo using the application integratior and it was working fine.

If i want to have another web application which has some other parameters along with the username and password.

For yahoo i had just specified the user=<MappedUser>&passwd=<MappedPassword> for the URI templet for the user Mapping

For my new web applcation

Where should i specify the other parameters?

How to do it ?

Explain me in detail.

Thanks in advance.
