Guest/Member location on non-vb pages for who's online?

[Kathy]

I know there is a hack for who's online to be displayed on non-vb page. But I think what I'm looking for is different.

I use php for the extension of all the pages of my website, non-vb, so that I use header.inc and footer.inc for those pages...to easily update the header and footers when needed.

Is there any way to add a snip of code to keep track of guests/members on those non-vb pages using their vb session hash?

I was just thinking if there was a simple way to add a bit of code to the header...it would then show those guests/members locations on "who's online" ?

Is this already done and I don't know what to call this?

Thanks for any help you can provide.
