The problem is, I want an automatic way to know when sites have updated, so my program doesn't have to keep checking all the feeds to see if they've updated. I know that there are ping servers that blogs ping when they've updated, like blo.gs and weblogs.com. But, I am unsure about how to use this to my advantage. Can anyone point me in the right direction? Also, does anyone know if RSS XML docs have a way to query them for the last updated time? That way, I don't actually have to download the whole doc to see if its updated (I know HTML has this capability). Thanks, James | ||||||
