Webbrowser filedownload handling files pushed from websites

Question

Hello all,

I have an application that I am using a webbrowser class to authenticate to a site and download a report. Unfortunately the report is generated on the fly and pushed out to the browser via java code so I do not have access to a "file" URL. 

Currently the pushed file attempts to open in a regular browser outside the Application.

How can I capture this pushed file and save it to a local path?

I have found tons of information on handling the scenario where one has a file URL, I have found no information on handling a file pushed (where the file download starts as soon as I click the link) 

Any assistance is greatly appreciated.
