As far as I know, XMLHttpRequest only lets you retrieve information from the local server as part of a security measure. If you want to retrieve information from a remote server you need some sort of proxy.

As an aside, your code is IE-specific. Okay for testing, but you'd have to change that for production use - just in case you didn't know.

i am using it for ie 6 only... are u sue abt the "XMLHttpRequest only lets you retrieve information "

w3 words
The XMLHttpRequest object is an interface exposed by a scripting engine that allows scripts to perform HTTP client functionality, such as submitting form data or loading data from a server.

why not use a system call and wget? ofcourse, this will only work if your using something like php, as javascript is client side only.

It would help if you took the time to produce a vaguely coherent reply. If you expect people to spend some of their time giving you an answer, surely the least you can do is spend a few seconds making your post understandable.

In any case, yes, I'm fairly sure, assuming you meant "sure" rather than "sue" and "about" rather than "abt". See here.

you can run this script code from your computer as "local file" but you can't run from "internet location" ;)
because
1 : it's unsafe! are you sure the object xmlhttp from microsoft server exists on every computer??
2 : access from client-to-server by getting GET is denied

you want show other page in your page?

soultion:
1 : write a server side (or server run) script!
2 : use frame with src propety for showing other page
