Re: server-side redirect thingy?

Thanks for your reply,

Of course I could use this method, I could even do this client-side using
JS.  My question is, can it be done so that you refer to a script as the src
of the image, and the script returns the correct image?

So, if I put <img src="header.pl">, it would display header.png or
header.gif, depending upon the browser.

I want something that would be nicely invisible, that would not require me
to chop up every page in a scripting language.

Hi Tim,

I use a browser sniffer in my ASP code and then render the appropriate HTML
for
various  browsers.

In your case the code would look something like this...
<%
browserSniff();  //calling the function that would reveal the client browser
var imageTag = (ie5)?"someimage.png":"someimage.gif";
%>

and in the html...

<img src="<% =imgageTag %>">

I don't use PHP, but i'd imagine that the implementation would be very
similar.
