[Solved] Redirect ignoring QueryString parameters after deploy in IIS Server

I would like to have a single aspx page that can be passed a simple url parameter that will then load a .rpt file.

This works perfectly on my local machine running Win10. The report runs fine if I run it like report1.aspx or report2.aspx

If I run it as website.com/report1.aspx?report="report2.aspx" it ignores the parameter passed and instead loads report1.aspx (completely different behavior that on the win10 box running IIS).

I have tried this on both a IIS8 server and an IIS 10 server (Win 10 also runs iis 10).

I am not understanding why the applications is accepting the passed parameter on one machine but not the other?
