# Self-TJ
To the Masters of b3ta.
Why not include some sort of 'Refresh' link that simply links to the board?
If I understand correctly, people doing 'Refresh' or F5 will have all the images reloaded too, with quite a waste of bandwidth/time...

# because it caches the images so it doesn't cause problems to refreshers
and a button like that would eat up the b3ta bandwidth

# I am not sure...
I did some experimetns, and F5 seems to hit a second time my server's logs.
But maybe it was just an HTTP HEAD command... dunno.

# ??
At least in Netscape, I see no difference between F5 and CtrlF5.
Will experiment more...

# I believe in netcrap
shift-F5 is the equivalent of interweb exploder's ctrl-F5

# it's usually a normal GET + if-modified-since headers...

# Yeah, I agree
It would be nice to have a 'live' version of the board, which works more like live chat.

# but then your reading something and poof
its gone besides someone made a page like that a while ago!

# F5 (normal reload) will in most browsers
re-request the page, and then request the images IF they have changed since last requested (if-modified-since / e-tag headers).

A click on a link to an already downloaded page that has proper headers set (no-cache etc.) will reload the page, but will probably NOT re-request the images. This will reduce the bandwidth for the image servers, but only by about a 300 bytes per request or so, assuming the webservers for the images are well-behaved. Ofcourse 300 bytes x 10,000 unnessisary requests per image is still 3Mb per image..

You can check this on firefox if you have HTTP headers plugin (not installed now, sorry).
