problem with passing the cognos 8.4.1 url from another application

[smtest]

I am trying to pass the url(that contains path to the specific folder in 8.4.1 with username and passwords) from another application. But some how it is using only a blank page. It does pass the url but it doesnt render. Because i can copy the address and paste it on another window it works. Please advice.
I was talking with the web team and they suggested it has to do with "Post" instead of "Get" in II7.
please advice
thanks
