rewriting URL to hide from user

Hello, we currently have an application hosted on IIS.  This is a third party app that runs reports, and passes some of the parameters in the URL when the report is run.  There is one specific dashboard view that does this, that we want to hide the URL from the users.  Is this possible via the URL rewrite module?  This dashboard has 5 links, that has a long string of parameters and we want the user to only see something likehttps://domain.com/financial, instead of https://domain.com/Main.aspx?hiddensections=header%2Cpath%2CdockTop%2CdockLeft%2Cfooter&evt=2048001&hiddensections=header%2Cpath%2CdockTop%2CdockLeft%2Cfooter&src=Main.aspx.2048001&documentID=693C426145B4E1DF4A4C0CAF63858196&currentViewMedia=1&visMode=0&Server=servername&Project=project&Port=39321&share=1

I monkeyed around with outbound rules, but they had no effect.  I applied them to the site folder within default web site.  When I tried it on the default web site and iis server level, the entire site broke although I tried to set up the conditional rules to only apply to that URL string.  Am I barking up the wrong tree?
