Hi guys,

My problem is when I submit my form and use the IE Back button, I got the error message "The page can not be displayed...."
below is how I do with the form

The First:
1. Page 1: submit form, method = post, action = Page 2
2. Page 2: process the form data and redirect (header/javascript) to Page 3
3. Page 3: hit the IE Back button and get the error

The Second:
1. Page 1: submit form, method = post, action = Page 2
2. Page 2: process the form data and stay in Page 2
3a. Page 2: hit the IE Back button, working properly
---------------------
3b. Page 2: click a hyperlink to page 3
4. Page 3: hit the IE Back button and get the error

I don't know why I get this error and how to solve....
need your help!

I believe your issue is that when you are hitting the back button, it is taking you to page 2 which processes the data, and tries to process it a second time resulting in an error. There are a few ways to get around this problem.

1. You can put a back button on your page that is simply a hyperlink back to the first page, skipping page 2. But anyone using the browser back button will still encounter this error.

2. (unverified) I've seen posts with people having similar problems and solving them using method = get instead. This will put your values into your URL though, which may be a problem. You could always encrypt them.

3. I'm not sure if you are using any PHP, ASP, etc for processing the data on page 2, but in PHP you can use the 'HTTP_REFERER' variable to direct the page. If the value is the URL of page 1 then process normally, if from page 3 then automatically direct to page 1 without processing. This is often considered an untrusted technique, however.

Does this currently work in firefox?

hi Nahele,
I solved this problem, yep... you're right about the redirect... i changed from javascript (window.location) into php header function and the site ran smoothly
thank you

Glad it worked out.
