Check if browser is NOT I.E.

On a page optimised for IE, I'd like to check if the browser type is other
than IE, so I can direct them to another page.

How can I modify the code below to redirect to indextext.asp if they aren't
using IE? I've tried changing the = for <>, but get a syntax error.

Thanks

USER_AGENT = Request.ServerV ariables("HTTP_ USER_AGENT")
IS_IE = InStr(USER_AGEN T,"MSIE")
if IS_IE then
response.redire ct "indextext. asp"
end if

I hope this is not for a public website... browser sniffing is bad practice.

The code you posted works fine on my machine, what specific syntax error are
you receiving?

For one, it's unreliable. Some browsers even let you input any user Agent
string you want. It also makes maintenance a nightmare. You are better off
writing semantically correct code that can be displayed in all web browsers.

The code I posted does work for detecting if it's IE - what I want to do is
modify it to redirect the visitor to a different page if they are using a
browser other that IE. If I change the = sign to <> (as below) , the browser
comes up with "Syntax error" and points to the <>.

Other points:- what on earth is "Browser sniffing"? I got the code from this
forum in the first place in answer to a question on how I can direct
visitors to pages optimised for their browser, and that is exactly what I
use the code for. Why on earth is directing visitors to pages designed for
their browser a bad thing????????

Thanks,

David

did you mean to do something like this? there are a couple of syntax
errors in the code you pasted.

USER_AGENT = Request.ServerV ariables("HTTP_ USER_AGENT")
IS_IE = InStr(USER_AGEN T,"MSIE")
if IS_IE <> 0 then
response.redire ct "indextext. asp"
end if

i think it's something of an ideological thing -- it is ALWAYS better to
write universally compatible code rather than code that requires you to
have different pages for different browsers. also, the person whose namei
cant remember pointed out quite rightly that some non-ie browsers, like
opera which i use, can be set to spoof as internet explorer to avoid just
those kinds of mechanisms (if i technically can see a page, i want the
chance to do that, not be sent to a bare-bones version). it more or less
undermines doing browser-sniffing -- checking the user's browser and
coding differently for it -- in the first place.

The need to redirect implies a deficiency in your "optimized for IE" page.
This may, as Jenny suggests, be a matter of ideology, but believe me, the
decision to code to standards rather than browsers will pay dividends down
the line.

I personally have no pity for users who access my sites with browsers that
don't understand HTML 4, ECMAScript v3, DOM Level 1 (most of it, anyway) or
CSS 1. Note that these are minima, and I do not DENY anyone on the basis of
his browser. I merely lack respect for his browser choice and make no
attempt to accommodate it. Those standards, after all, are each several
years old.

I partly accommodate those with scripting or cookies turned off, but often
require one or both for users who want to use one of my *applications* with
full functionality.

What does "partly" mean here? One example is popup navigational menus. Our
intranet site has them. But if the scripting to open the menu fails for any
reason (such as crappy browser or scripting turned off), the user is sent to
a page that lists all of the links in the drop-down menu.

Does that user experience the full glory of our navigational menus? Who
cares? Does he get the same opportunity to access information? Yes. And that
is truly the only thing that matters when considering divergence from
standards.

To do that, you would be stuck with HTML 3.2, unless you determined the
browser. Semantically correct code for NS7 may not work in NS4.x.

Huh?!!! What in the world are you talking about?! Semantically correct
code is far more likely to work in NS4 than not. Can you give me an example
of where this is not true?

The closest I will ever come to browser sniffing is hiding my CSS from NS4
and letting it apply it's default presentation to semantically correct HTML,
since NS4 doesn't properly implement CSS. But this is NOT browser sniffing.
