| How to force the user to download a file instead of opening it up in an
controlled environment within the browser (i.e. MS Word/Adobe Acrobat)
Categories : Browsers, PHP, HTTP | | | Most of the browsers, especially Internet Explorer, behave in different ways. Hence it become necessary to use Browser detection to fix the non standard behavior of the browser. This is a browser sniffer class that can be used for the above purpose.

Surely the above script will generate a redundant entry
in the browsers history list (you know, a `back` button
problem)?
Wouldn`t it be better to run a script on the basis of the
browser`s initial request, i.e. keep it all happening at
the server end?
There`s a perl cgi solution along these lines at
http://www.wirewd.com/wpt/tool/redir.html
Anybody know how to write this sort of thing in php?
(sorry, I`m not a coder - more of a paster!)

This script is a really good idea but it just doesn`t
work...
| | | | John Walsh wrote : 228
.... oh yes it does (oh no it doesn`t) ...
Here`s an example of it working
http://www.nottingham.ac.uk/tsd/
You get a dhtml page for 4x`s and text only for the rest.
Obviously you wont be able to see the script, but it is
the exact same thing as that avaliable from wirewd.com

Just an idea.. Will something like this work? (I have no time to test at this moment)... :
<?php
$browser = $HTTP_USER_AGENT;
$a = strstr($browser , "MSIE");
$z = strlen($a);
/* z return a number >0 if MSIE is matched and 0 if not */
if ($z = 0 )
{$loc = "ns.htm";}
else { $loc = "ie.htm";}
/* change the url: index1 is for IE and index2 for other browsers */
header("location: $loc");
?>
This would remove the "back-button" problem wouldn`t it?

Sorry... I think will do it this way:
<?
$browser = $HTTP_USER_AGENT;
$a = strstr($browser , "MSIE");
$z = strlen($a);
if ($z = 0 ) {
$location = "ns/";
}
else {
$location = "ie/";
}
$mylocation = $SERVER_NAME.$REDIRECT_URL;
$newlocation = $mylocation.$location;
header("location: $newlocation");
?>
This would work I guess... (have no chance to check it right now)
