RSS help

How to support RSS in a website so that people can subscribe? I googled and found lots of documents about how to subscribe and about news readers, but not talking about how to support RSS functionality in a website?
   
  Thanks,
  Dave

Developing Feeds with RSS and Atom by Ben Hammersley

There are many similar books.

Thanks.

If you can save out entries that you want made into an RSS feed into
static files, you could use one of the Apache modules which exist
to serve up a directory index in RSS format. This is a good solution
because normally, past entries in a feed never change once they're
generated.

If you want it to be generated completely dynamically within your
application, I'd recommend the Rome library (https://rome.dev.java.net)
which includes generators for Atom and all varieties of RSS found in
the wild.

Send the Last-Modified HTTP header from your web application and check
for a If-Modified-Since request header. If you detect that the client
has a fresh version of the feed, respond with a 304 (Not Modified) code.

Is there a way that NewsReader knows whether a page has been updated? How? the page is dynamic collecting data from database.
  Thanks!

The NewsReader /polls/ the feed regularly.
As such there is no mechanism for notifying changes.

Thanks,
   
  It semms that it is easy to write the XML file for a Feed. But how 
does NewsReader know the page (pointed by feed link) has been changed, 
what are the changes, updated time?
   
  I have not got the idea yet :)

I went thru the same thing. Basically all you need to do is make an XML file
and put it on a web server some place. Then provide the link. People can
copy the link and paste it into any rss reader, or if their browser
understands what to do, it will add the rss feed link to the integrated
reader. 

So you need to create the XML file, save that file to your web server. Then
provide a link for people to use.
