I am more likely to install ISA on my server, for the web caching facility it has, but at this moment im reading the chm file from the MS site.

so far i understand what’s its on about, but have a look at this pic.



Client 1 and 2 websites are cached on the ISA Server computer, this speeds web browsing. Also with ISA you can set a time to download the content from the web to your server. fair enough, but what happens if the content on the server is 4 hours old? does client one retrieve the updated content from the site, or the old content from the ISA server?
