Hi Nick, all, 
 
First of all thx for your reply. 
I have managed to find another work around for this problem. The main
idea is to keep a counter in the session. This counter is passed to the
html page, through the context, and is incremented by one when the user
presses the 'submit' button. When the request is received the value of
the counter is compared to the value stored in the session. If the two
values differ by one, then it is a new request. Else it means that the
request came from a 'refresh' without the user pressing the submit
button. 
This solution seems to work but it is a little complicated, so I would
still be interested in a simpler, more straightforward solution, as the
one you suggested. Unfortunatelly, I am a newbie in webmacro, so could
you please indicate in more detail how exactly a redirect is
implemented in webmacro? A code snippet would be very appreciated. 
 
Thx in advance, 
 
Nikolaos

 <pre wrap="">Hi Nikolaos

The simple solution is to use a post to submit the data but to redirect
to the display page. That way the post is not repeated as the page has
been reached as a result of a GET.

Nick

    <pre wrap="">Hi all,
I am using webmacro to develop a (small) web-based application.
I am facing a problem in my application. The problem occurs when the 
user re-submits a request, using one of the following methods:

1. reloading result page using Refresh/Reload browser button,
2. clicking Back and then Forward browser buttons,
3. returning back to HTML FORM after submission and clicking Submit 
button on the form again.

Browsers usually, display a warning message when the same POST request

and obscure for an average user. Also, some browsers do not ask for 
confirmation at all.
Is it possible to get rid of this kind of inconvenience?
Is there any hint you can give me for this phenomenon?
Can webmacro handle this?
Any source code would be appreciated.

Hi,

WebMacro is not a web framework, it is just a view layer (renderer). As 
such WebMacro does not provide any functionality relating to the 
double-post problem.

Cheers
