Question

Have some Javascript that I need to work via the following:

://localhost

://servername

:/www.domainnamefortheserver.com

When I run the script from http://servername with an IFRAME referencing the domain - it does not load.

Is there a way to get the Javascript security model to recognize the server name, localhost and the domain as the same "domain"?

Thanks

Answer 1

If you are running on UNIX you can edit /etc/hosts to give a fake DNS entry for your server.

eg.

127.0.0.1 localhost www.domainnamefortheserver.com

Then you can always connect to it as the correct name even when it s not on the live site yet. Don t try and break the javascript security directly.

This will also work on OSX. Windows works differently, I expect.

Answer 2

If you are using a server-side language to generate the page, you may be able to set the security domain like so:

document.domain = $CURRENT_HOSTNAME;

So the security domain will be the domain the user requested. This is a shot in the dark, but I hope it helps nonetheless.

Answer 3

Use root relative URIs:

href="/foo/bar"

rather than absolute URIs:

href="http://example.com/foo/bar"

That way the document will be loaded from the same hostname.

Answer 4

What do you mean by

my references are to the domain name

?

If you load scripts in your page on http://servername (using <script src= >), they will have access to everything on http://servername, even if they come from another domain.

However, if you try to make AJAX calls to the other domain, then you have a problem. You can use the trick explained by Christopher, ie making aliases to the domain.
