problem?ftp'ing to server

Archived from groups: alt.comp.periphs.webcam (More info?)

i am new to web camming. I have some software to auto ftp a snapshot
every minute or so to my webspace of my ISP via a bb connection. I
have a webpage written which includes some java to auto refresh the
page every 20 secs. Despite a new image being ftp'd every minute and a
refresh every 20 secs, i dont get a new image shown every minute,its
more like every 5 or 6 minutes. Perhaps the webpage server of my isp
has some kind of cache arrangement so that it doesnt always output the
very latest pic?. How can i overcome this problem?
