setDelayBeforeLoad

void setDelayBeforeLoad(isDelay)

Some browsers (notably IE) do not load images from thier cache when content is updated using innerHTML. As a result, each image is re-requested from the server even though the image exists in the cache. To work around this issue, AjaxAnywhere preloads images present in the new content and intrduces a brief dely (default of 100 milleseconds) before calling innerHTML. See http://support.microsoft.com/default.aspx?scid=kb;en-us;319546 for further details. This function can be used to change this behaviour.

Parameters:
boolean - ) isDelay
