Access Denied

David Dorn got an error message from a Web server that made him wonder what on earth the webmaster had been drinking… and provides an example of one of things you should never do as a Webmaster

I spend a lot of time on the Worldwide Web – it comes with the territory – and as such, I’ve seen an awful lot of websites. But one I surfed to yesterday while I was trying to find some information about a particular software package – and this was a piece of research that could have earned its author quite a bit of money – delivered such an insulting error message that I was totally aghast!

So much so, in fact, that I captured the HTML for the page it threw up, which I’ll reproduce here for your delectation:

Access denied: incompatible browser.


The server has detected that you are using a browser that is incompatible with Internet standards (probably Microsoft Internet Explorer). The server is programmed to deny requests from such browsers.

To view this site, please switch your browser. Compatible browsers may be obtained from
Amaya,
Mozilla,
Netscape,
Opera,
and others. (See the browser list at browserwatch.com for a full list.)

What do you make of that? Effectively, this system operator has blocked 90% of his potential traffic from ever getting to his site. Now, I know how easy it is to slip a little JavaScript into a Web page to identify which browser your reader is using, and divert him or her to a suitable page. That’s one thing – and it’s not a bad idea if you’re serving up some clever scripting – but to set up the server to reject requests from a particular set of browsers (the set that just happens to be the biggest, and includes every AOLer) is, to my mind, bordering on lunacy.

I can see a situation where you might want to keep a Web site select, for a very small set of closely defined users – a closed user group, if you will. I suppose you could use this technique and let your users know that they must use, for instance, Opera, and set it to announce itself with a particular set of completely non-standard parameters. That seems like a lot of work, though, and isn’t particularly secure.

No, this guy is simply being bloody-minded. He’s got a bee in his bonnet about Internet Explorer or AOL – or both – and he’s making his own personal preferences known.

Well, if he’s reading this, he may as well know that he’s lost himself a potentially big chunk of business. How arrogant!
