for one reason or another I need for javascript to access a webserver on the localhost. This localhost webserver is under our control so we can have whatever software running in it.
How would you do this? I've seen things like YQL but this accesses another domain from the internet. This kind of access causes a lot of problems with firewalls and such. So I want to access the same computer that the browser is running on.
How would you do this with javascript and whatever software running on the localhost server?
Also, the javascript is being run from an internet site. And the localhost server will not be running on the same port are the internet website is.
Is this possible to do? I know about the cross-domain restrictions but I've also seen there are ways around them such as YQL. How does something like YQL work? How would you reimplement it?
You could try something like JSONP.
In JSONP, you use dynamically created script tags to access things in other domains. The URL can be used to pass data to the server, and the returned script can call a callback to return data. As far as I remember, there are no special restrictions on making requests to localhost (unlike the filesystem), but I might be wrong.
