Hi *,
From what I understand, having the following DTML and/or HTML tags *should* disable IE from caching previously entered values in form fields...
<dtml-call "RESPONSE.setHeader('Expires', '-1')"> <dtml-call "RESPONSE.setHeader('Pragma', 'no-cache')"> <dtml-call "RESPONSE.setHeader('Cache-Control', 'no-cache')">
<HTML> <HEAD> <TITLE></TITLE> <META HTTP-EQUIV="Expires" CONTENT="-1"> <META HTTP-EQUIV="Pragma" CONTENT="no-cache"> <META HTTP-EQUIV="Cache-Control" CONTENT="no-cache"> </HEAD>
Yet somehow IE remembers these values, and if I begin to enter say "3" IE will remembered the previous entered values 3, 33, 311 etc. and display a nice little IE drop-down-like-box below a standard HTML text input form field with these values.
Is there any way to disable this?
I'm quite sure that this is not something which could be prevented by a trick from the normal http/html standards toolbox - because, AFAIK, remembering form entries is not decribed in any standard. But maybe you could fool internet-explorer. Maybe alter the names of the form fields, e.g. <input type="text" name="textfield_3232"> where everything after the underscore is a random value. Sadly, this would make getting to the form values a little bit more complicated. Maybe altering the name attribut of the submit form or introducing a randomly named hidden input type would do it. Or calling the form with a randomly choosen attribute: <a href="your/form/URL?param=f09j3209ruwijf"> What I want to get at is that the only way I see to prevent this behavior of IE is to confuse it about the "identity" of the form, so that it isn't able to show previously entered values. I assume google can tell you how IE identifies the forms. HTH, oliver
