When using the get method on a form what is the limit to the Querystring?
IE4 and 5 limit the character length of querystrings to about 2000 characters, and other browsers may accept as few as 1000. You can always use a hidden form field to pass the data.
by the spec I *think* it's 256 chars. IE can handle more, though - which is really something of a dumb strategy if you ask me - as IE can then be used for buffer overflow attacks and things like the recent hotmail hole.
