Newsprout Preview Proxy

This proxy server allows you to see what your web site will look like before DNS changes are complete.

Enter the URL of your new site below, and enter the IP address of the server where it is set up. Click the button to see what it will look like when the DNS has updated:

Features

The proxy server makes the connection to the server on your behalf:

You don't have to change your hosts file
URLs on your site are redirected to this proxy server
If you browse away from the test site to a live site, then you are redirected to that site
HTTP basic authentication works
Cookies work, but might be a little weird (promiscuous)

Limitations

A few things are not supported:

This proxy does not support partial loading: you have to wait for the proxy to get the whole page and ajust the links before it sends it back to you.
You can expect it to be slow, because HTML pages are decomposed and rewritten.
Javascript-heavy and flash sites tend to end up loading the "real" site, since IP addresses in scripts are generally not rewritten.
Meta refresh requests with an absolute URL are not rewritten.
Non-HTTP protocols, and HTTP on ports other than port 80 are not supported (most of these are not virtual hosts anyhow, so you can browse to them directly).

If your new site and your old site are identical, you should use a browser plugin to show which URLs you are visiting (e.g. firebug for firefox).

Bugs

Yep, there's bugs, there are, and not just in the grammar of this sentence. If you see one, don't panic - your site probably looks fine!

Error handling is pretty much non-existent - expect blank pages.
The proxy can confuse character set encodings, and leave strange droppings like Â in your output.
This proxy should not be used for security sensitive work, since different sites are rewritten into a single domain.
The HTTP referer header is not handled consistently.
Links to foreign sites will be rejected by the server of the IP address you give: the software is too dumb to figure out whether you want the real fbcdn.com or the fbcdn.com at the IP address you supplied.
This service is supplied as-is without any guarantee as to whether it works, etc. Any assumptions you make about its manner of operation are entirely your own.
