How would I get the file extension from a web address loaded in an IE object?

[Internetwiz]

Hey peoples.
Ok, so here's what I want to do.

I want to be browsing in one IE object normally until I hit a .MP4 file extension. (AKA, I clicked a link to randommoviename.mp4).

When the IE object encounters the link in question, I want it to stop loading and load the address in a partner IEObject.

When browsing using IEObject-1 and I click a link to a ,mp4 extension, I want stop and load that web address in IEObject-2.


And I am going to be using this code in a few projects, so being able to do this with file extensions that I specify is important. One might load videos, another music, and another project might see it loading images.

Thanks for your time!
