Location of cached html file

Hello,

I have a program which displays a webpage in an embedded browser window and I need to parse through the source of the page to grab a link.  When I find the page in my temporary internet files it shows me the cache name: *.htm but I cannot locate that file anywhere.

I am familiar with the winhttp library to grab internet pages but this page has a redirect involved so the result I get from that is not the final page as needed.

Thanks,
Evan
