Hi,

does not work???

Ok, there is a meta tag thing you can do which is not as good.

there should be help on this at www.htmlhelp.com

BUT the header() is better.

MrAlaska

Some browsers do not understand the redirect command sent by header() and some browsers (such as Opera) have that functionality turned off by default. If you use the header() function, you also need to add a few more lines:

header("Location: example.php");
echo "You didn't go where you were supposed to! ";
echo "<a href='example.php'>CLICK HERE</a>";
exit; // so the rest of the page does not display

Personally, I prefer to use the 'include' directive, it is more foolproof and you do not need to worry about passing your variables.

well... that should work. maybe try using the full url on yr header call, ie:

header("Location: http://mydomain/login.php");

header("Location: [url]http://[/url]$HTTP_HOST/login.php");

of course the header call has to come before any text output (which sends a default header)... so i usually test with headers_sent:

if(!headers_sent())
header("Location: [url]http://[/url]$HTTP_HOST/foo.php");
else{
// do a java script redirect on a timer here... i don't have the syntax available right now, but put it on a timer
echo "go <a href=\"login.php\">here</a>";
die; // don't go any further!
}
