Internet Explorer does not follows redirect, while Firefox does
Hi all. I don't think this is a specific Zope problem. However, I'm experiencing it in a Zope context, and this is why I'm here asking. In a custom Zope application, we have a problem with Internet Explorer. The application follows a "page -> submit -> redirect -> page" cycle. To state more clearly: the page presented to the user can have a link. When the user clicks on the link, something is done, and eventually the user is redirected to the same page which will display different data based on the results of its previous click. The problem is that when IE sees that the result page has the same URL as the first page it does not reload the page and instead shows me the cached version. The problem is not shown with Firefox. As far as I can understand, this is an HTTP header issue, but I would like to know if anyone already has experienced this problem, and has some solution about it.

Ok, I've been able to experiment. All my pages have the following in the <head> section: <meta http-equiv="Cache-Control" content="no-cache"> <meta http-equiv="Pragma" content="no-cache"> <meta http-equiv="Expires" content="Date.Now"> <meta http-equiv="Pragma-directive" content="no-cache"> <meta http-equiv="cache-directive" content="no-cache"> Also, I added, before every redirect, the following: request.get('RESPONSE').setHeader('pragma', 'no-cache') Any suggestion?

I have forgotten the exact details, but some time back I found it necessary to pad out the body of the redirect page in order to make IE perform as intended. It may have been for an older version of IE, and the padding just needed to be a certain number of bytes. I think I came across a later reference to the problem. Have you googled for info? Padding follows.

I guess your response means it does not solve your problem. However, I won't be able to help you further. It's just a trick that worked for me. Your use case must be different then. cb ----- Original Message ----- From: "Marco Bizzarri" <marco.bizzarri@gmail.com> To: "Kees de Brabander" <cj.de.brabander@hccnet.nl> Cc: "Zope Users Mailing List" <zope@zope.org> Sent: Thursday, June 01, 2006 12:49 PM Subject: Re: [Zope] Internet Explorer does not follows redirect,while Firefox does
