I have an asp page that has a ftp link to a pdf file.
Well problem is if someone adds to the pdf file then they are just grabbing the cache version and this is causing a big issue.

Kind of talked about this in past and i gotta get a solution to this.
When i look at my temp files i see there is no expiration date set. Is there a way to do this?

I have tried the different headers on top of the page and settings on IIS which works fine if its actually content on that page. But the content stored from the link stays lurking in there. argh...

We use Internet explorer ie7 mostly.
