DNS modification?

[esuvb]

Hi All,

Would be grateful if anyone could help. This is a more detail description to my previous question.

The scenario is this:
A user on his/her web browser typed an url, browser send url to DNS to check and found it to be invalid, and the web browser display a error page to the user.

Instead of the above process flow, is it possible that we could intercept the invalid result from the DNS server, send user typed url as keywords to a search engine, and display the search results to this user?

At the moment we have a javascript which could send keywords to Yahoo, and Yahoo returns a xml file to us and then we customize our own search page.
This is so that we could return it to the user's web browser.

Best Regards,

Wilson

I am not an expert, but I'm thinking a proxy server should be able to do this.

A proxy server sits between your LAN workstations and the gateway to the Internet. (I'm recalling how Internet access at hotels require first agreeing to an AUP, billing agreement, etc, this proxy page is sent regardless of the Web site you typed into your browser.)

I know it's possible, although I don't know the details, because Earthlink is actually doing this now. When web-browsing using Earthlink, instead of a "page not found" you get a listing of search suggestions from Yahoo. I wouldn't mind that so much, might even find it useful, except for the fact that this is set so it disables the back button! I've used Earthlink for web-browsing for several years and this is the first thing they've done that comes across to me as anti-user.

(So, anyway, if you do this, please don't disable the back button.)
