How to determine age of rss feeds

Hi there

I wish to write some script which can cache the RSS feeds on my server as long as they not updated on the remote server.

Please give me some clue how to go about it.

Could poll on interval using HEAD request (run "%A.*%S" string through "date" to expand):

Code:

HEAD $URI HTTP/1.0 If-Modified-Since: %A, %d-%b-%y %H:%M:%S

and parse response for string "304 Not modified":

Code:

HTTP/1.0 304 Not modified

HEAD request being cheap (bandwidth): only header is returned.
