HTTPS Connection customization

So I'm trying to use the HTTPS connection to login to Saleforce which has the following format:

 

https://login.salesforce.com/?un=USERNAME&pw=PASSWORD

 

It doesn't work if I put my USERNAME and PASSWORD into the User/Password inputs as the actual wording is "un" and "pw".  

I would love to just put in the above string AS IS and not have Knime manipualte it.  When I do that though, it tells me I can't have paths, queries, etc, in the host string.

Any ideas??

The username and password fields are for BASIC http authentication which is different from sending the credentials as part of the URL.
