I'm having an odd problem with my website refreshing, I have two webcams on it, the pictures from the webcam are updating onto the server but not refreshing on the browser, at least not on my machine anyway, but when other people view it, it seems to be ok...the page is set to refresh every 30 secs or so..and you can see it refresh all the graphics except the webcam picture...
why? - anyone any ideas?
the site is http://www.robsanderson.freeserve.co.uk
No, its not refreshing on mine either. What's happening is that my browser doesn't realise the picture has changed and is just pulling the previous image out of its cache.
This might help:
<META HTTP-EQUIV="Expires" CONTENT="Tue, 04 Dec 1993 21:29:02 GMT">
Stick it between the <head> and </head>. It tells the browser that the page expires on 4th dec 1993. This means that, unless you go back in time, the page is always expired and so the browser "should" load a new version from the server every time.
There is another meta tag which tells the browser not to cache the page in the first place but I can't remember what it is. I have used it and I don't think it works very well anyway.

cheers, done it, uploading now, i'll see if it works in a sec!!
Yeh the other way of not caching is
<META HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE">
But I believe IE 5 can ignore it.
As Jinx says, the expiry date is the best way of doing
such a thang..
