We have a chat application that is mobile responsive. However, it is hosted on another server and on a subdomain. ([login to view URL])
We want to put that application within our regular root domain website ([login to view URL]) It will probably have to be in an iframe but still serve it from the other server.
Meanwhile the url of the browser must still display the regular root domain. ([login to view URL])
I have seen it done before and is probably very simple for someone who knows what they are doing. I am guessing php will be required. HTML skills also.
Message me for more details.
