We only have IIS; our site only uses VB.Net. No perl, no PHP. I don't know what a cron job is, but I know I can't access the command line; I'd have to go through corporate IT and they have said no already to that.
The feed is a Yahoo Pipes RSS we use to feed our blogs, because the blog software we are required by our company to use does not have a way to build a group blog. Pipes caches a LOT, and the people on the Pipes support forums say the only way to get around that is to WGET it. The cache for Pipes is literally as long as 90 minutes, and Chris Holcomb can be really annoying in person when his latest blog doesn't post, despite how nice he seems when you see him on the news.
