Yahoo's RSS Reader

This is probably too specific for SDMB, but I am “literally” (not really) tearing my hair out. A couple of questions:

  1. When I try to ping Yahoo to tell them my RSS feed is updated I get an error: “Refresh failed. Feed not found: http://www.mysite.com/rss/myfeed.xml

I am using “http://api.my.yahoo.com/rss/ping?u=http://www.mysite.com/rss/myfeed.xml” to do the ping. I thought maybe I had a bad XML/RSS document, but I ran it through feed validator. I also copied another site’s XML/RSS doc and put it in place of mine. The ping also failed for it.

  1. What I really want to do is have the Yahoo RSS reader not do any caching and just look for refreshes on some regular basis (5 minutes?). My RSS feeds are custom created for each user so there is no use caching and proxying them. If I use “RSS Reader” or my own RSS widget things work just fine. Yahoo is just being too clever and its reader never sees my new items (or I give up after several hours).

If anyone has a contact at Yahoo I’d really appreciate a referral. I’m trying to get together a demo for early Jan and it’s looking bleak.
