I remember Matt Sharkey employing JavaScript to disable reloads on
resizing for PerlChameleon, but perhaps setting an appropriate value
for the HTTP expiration time might help.  The default is to have an
expiration of a year ago, but maybe you want an expiration of 10
minutes or an hour from now?  It depends on how soon, on average, your
content might become outdated.
