refresh on back button or goBack(-1)

[gwrman]

Anyone know of a way to produce Something like the "onclick=history.go(-1)" command, except it would grab a fresh version of the page from the server and not just pull the old page out of the users cache.

Just set the page to specify no caching using the:

<META HTTP-EQUIV="Pragma" CONTENT="no-cache">

tag.

well- more details on the situation...

teh page i want refreshed is actually an iframed page that generates a captcha image.

<iframe id="captcha" height="23px" width="86px" frameborder="0" marginwidth="0" marginheight="0" scrolling="no" src="../inc_captcha.asp"></iframe>


when the user hits back from the error page to reenter some details on the main page, i want that iframe to refresh, but not teh rest of teh page.
