What is the <ttl> tag for?

[buddha]

Hello,
Thanks for a great site. Am new to podcasting and I learned a lot from the forum. One question I havent found, what is the <ttl> tag for?

In different rss feeds I see different numbers inside the ttl tag. I'm not sure what to put here.

Many thanks.

Wow. Thanks. My google search didnt find that page... The tag was included in some of the forum tutorials on how to create a feed page, thats how I found out about it. It is a good idea indeed.
