I have the following code on files "a.php" and "b.php"
-----------------------------
FILE a.php
-----------------------------
<form action="a.php" method="post">
<input type="hidden" name="active" value="1">
<input type="submit" name="Submit" value="Send">
</form>
<?php
if (isset($_POST['active']) && $_POST['active'] == 1) {
?>
<script language="JavaS cript" type="text/JavaScript">
alert('Thank you.');
</script>
<?php ; } ?>
<a href="b.php">Go to b.php</a>
--------------------------
FILE b.php
--------------------------
<a href="#" onClick="histor y.back()">Back to a.php</a>
---------------------------
Works like this.
1. The user fills and sends the form in a.php
2. a.php loads and displays a thank you message
3. The user clicks on "Go to b.php"
4. b.php loads and the user clics on "Back to a.php"
5. a.php loads (I assume is loading from the cache") and displays thank
you message again, which should not occur!!!
I tried this on file a.php
<?php
if (isset($_POST['active']) && $_POST['active'] == 1) {
?>
<script language="JavaS cript" type="text/JavaScript">
if (!window.IWasHe re) {
alert('Thank you.');
var IWasHere = true;
}
</script>
<?php ; } ?>
But did not work. Also tried includding a pragma no-cache and expires
tags:
<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Expires" content="-1">
but did not work either.
Any ideas?
Thanks,

Change your link from history.back() to something a little simpler:
<a href="A.php?PHP AppendedTime">B ack to a.php</a>
And when b.php is sent to the browser, have php append the current
server time, in milliseconds, to the link.

Use PHP header() to have the browser no cache the pages, which is cheesy
IMO as you can just instead, use a target="thankyo u.html" on the form.

Yes, if that is the intent. But it depends on what the intent of a.php
and b.php use is.
Reading this group's FAQ (via sig below) will do wonders for you.

Question: Whats the most annoying thing on Usenet?
I must use history back because I want the user to come back not just
to the previous file (a.php), but also to the specific place in the
previous file where the user clicked in order to go to b.php. Besides,
theres is no only b.php, there could be b.php, c.php, ... etc.
Thanks.

I wonder if there is a way, using javacript, to detect the name of the
file (or title of the window) from which I am coming. For example:
1 I am in a.php and click a link that opens b.php
2 from b.php I click history.back()
3 back in a.php, using JS, I detect that the previous displayed window
was b.php (or the title of the window)
Thanks.

Hi,
I am about to write an application that will display all pdf files in a

Is there an easy way of doing this? I was thinking about somehow adding

printing onto an html page with a link to that file. How would I do
this though? Is this the simplest method or is there a better way of
