implementing download using a url call

[tanmay.kansara at gmail.com]

Hey

Sorry, I should make it more clear. We had a 3rd party that was serving stub builds and they have their URLs on various pages(random sites). We control the sub-domain, so i can send that traffic to wherever I want. I am looking to create logic that takes that incoming parameter and serves an exe file. 
With the logic I posted, the user gets the file, but also gets a new blank page. I would like to keep the user on the 3rd part website. 

Hope this clarifies. 

Thanks
