I have a page on my site, mysite.com/test, that I want to load a page on another site, test.jit.su, for example. I had set up my nameservers with my registrar (godaddy) so that I could add an A record for mysite.com/test that would point to test.jit.su. This has posed a few problems with email and other things on my webhost, so I'm going to change the nameservers to those of the webhost.
Is there still a way to do this without the A records?
DNS records can only set an alias on a domain (of any level), e.g. mydomain.com --> yotherdomain.com which also automatically implies redirects like mydomain.com/anything --> myotherdomain.com/anything but you can not do mydomain.com to one server and mydomain.com/anything to another server, if you want to do this you'll have to use HTTP redirect
